I agree that Tesla has clear strengths, like the vast amount of data they've collected from their cars, and their charging network, but it's also obvious that something is going very, very wrong with that company. The stock value is not reflecting that.

Loads of people trusted Huawei, even after all the hyperbole about backdoors for the government. It needed regulators banning Huawei to knock their share of the market and protect the homegrown spyware.

thephyber 8 hours ago | parent | next [-]

The government bans on Huawei were obviously do to three reasons: network security, economic competition, and politics.

Huawei doesn’t only make phones — they also make the cell network infrastructure and they sell it at much lower costs than American companies do. The US put pressure on allied countries to divest from Huawei infrastructure (especially 5G cell networking) to both avoid the security risks and to leave those allies with only American companies to buy from.

And we can’t forget that Trump very publicly used Huawei’s executive as a hostage to a negotiation.[1]

The traditional fix for this is to license the technology and do manufacturing for another carmaker to brand.

It's super common for brand X of car to actually be a rebadged Y with slightly different shaped body panels.

However, it only works if your product is good and you have decent margins. That means you have to compete with china cars, since the obvious thing for a western brand to do is to rebadge a chinese designed car and split the margins with the chinese designer/manufacturer.

Not sure if the product has to be good. Look at the lineage of my wife's car The 2019 Chevy Trax, based on the Buick Encore, based on the Opel/Vauxhall Mokka. It isn't a good car under any of the badges, but it does run, and is small, but the crazy thing is my Ford Ranger gets roughly the same milage as it. Note: the gas milage is probably an American issue, because it runs a naturally aspirated i4 gas engine instead of a more efficient turbo diesel.

There are people like me who still buy teslas. Buddy picked up his new Model Y couple weeks ago. The price and the whole package is fine. Zero interest financing is absolutely nice. Elon showed his real face during children rescue drama in Asia. With this defamation story it was well known who he is for years. Political involvement was the visible tip of an iceberg for everyone.

Now if you ask me if the German car managers are better I doubt it. Gassing apes by Volkswagen in US is on the same level as Elon. Mercedes guy was complaining about lazy workers too much. Only BMW guy was able to keep acceptable silence. Overall German equivalent of model Y is at least 20000€ more expensive than Elon‘s car.

Personally I don’t buy anything from China if I can. I am not brave and as the Ayways story showed clearly, that great Chinese car can quickly be without any service. Maybe it’s ok to lease such car for couple years, but I don’t want to have car after small accident for what no replacement parts are available.

Several years ago I wanted to buy an electric car. I didn’t like Musk, so my plan was “anything but Tesla.” Chevy Bolt was unavailable due to the fire problem. Cadillac Lyriq and Hyundai Ioniq 5 weren’t out yet.

I drove everything available to buy in my area. My real options were the Mustang Mach-e, Volvo XC40 Recharge, Hyundai Kona, Polestar 2. I decided to test drive a Model Y for completeness.

And CRAP.

The Model Y was obviously the best car. So much more refined than the other options. Way better charging network. 7 seat option. The only real downside was the zany CEO.

Fine, I thought. I’ll live with it.

I bought a Model Y and love it.

But.

I’ll never buy another Tesla. I have a bumper sticker disavowing the CEO. I paid off its loan so nobody would make money from me owning a Tesla. I honk support at the No Kings protestors outside the local Tesla facility.

I think the only thing that can save Tesla is a crash/buyout/relaunch. Get Musk out of the picture. Reset the stock price to something sane. Ditch the distractions. Release a Model 2. Keep expanding the SuperCharger network.

That’s a long hard road. Nobody involved makes money in that scenario. It’ll only happen when there are no other options.

As for me, I’m driving my Model Y until the wheels fall off. With the bumper sticker.

I spent a month in Spain driving a BYD daily and it was fine. I just don’t like the tackiness of the interior and not in love with the exterior either. The handling is also ok, nothing exciting. There’s something still very Chinese about these cars. Not saying that matters if you just want an affordable and reliable EV that takes you from point A to B. BYD can do that perfectly fine. I personally like the design of the Model Y (own one) very much, it also feels much more “alive” particularly the dual motor. There’s no comparison with the BYD I drove. Also never had any issues with build quality other than the charging port malfunctioning, and it was fixed outside my house, all I had to do was touch a button in the app to call service. FSD is pretty damn amazing. The tech is great and the updates do make the car better in many ways. I hope Tesla finds its way because apart from all the controversy they can make good cars.

Design is subjective (I like it), and build quality. Not sure, I don't have issues with mine except one where after 2 years frunk latch started failing. It was replaced in an hour when I went to service center.

Teslas are the cheapest EV for the features offered in Europe. I would gladly buy another car, but they are either more pricey, or lack features. (I did market research 2 years ago when I was buying Model Y, the closest one was ICE - RAV4 for similar price, but I didn't want ICE).

The entire car is a surveillance machine and the company is happy after a crash to taint the driver in the public’s eye if it will improve the image of their AutoPilot. It’s bad enough having to deal with car insurance after a crash without your car’s manufacturer blaming you in public, sending the recipients to news outlets.

Tesla has a monopoly on their car repairs, which reduces the number of mechanics qualified to work on it, increasing the cost and the wait time.

Teslas are a very expensive platform to service being largely an aluminum frame. Difficult+expensive to repair and replacements are expensive compared to cheaper cars which usually have more plastic. This means insurance is also expensive.

And this doesn’t even begin to get into the weirdness of their reputation for hiring private eyes to stalk employees and call the police to in an attempt to get an employee killed. Having an exec who has a ketamine problem and mania issues doesn’t lend itself to long term stability.

They failed, not because camera-based FSD is a silly idea (we drive with our eyes after all), but because it's a really hard problem. If they had won that bet, Tesla would justify its valuation.

It didn't fail imo - it was intended a low-volume product for next-gen Tesla tech - Ethernet based fieldbus, 48V systems, area controllers etc. The philosophy is the same like other high-end cars - you field test your latest experimental tech first in a car with lower sales but high margins - if your fancy stuff has a 1% failure rate, in a 100k production run, that's 1000 vehicles - high but manageable.

If you sell millions and its your main product, your company is over. This is the same playbook German manufacturers followed since forever. I bet the next gen Model 3 and robotaxi will get the cybertruck tech.

Cybertruck was supposed to be for the masses. The just weren't able to hit the price point required because of overly optimistic engineering assessments. I think the whole stainless steel construction concept didn't work as first designed.

And of course, Cybertruck design might not have been mass compatible buy being ugly. But that is subjective, if it was cheap and functional and without the political connotations it might have been different.

But it was certainty a risky bet.

alterom 8 hours ago | parent [-]

To be "for the masses", it would need to:

- be smaller

- have an actually usuable truck bed

- be painted (so rust isn't an issue)

- have a body that's not literally duck taped together in some places and can easily snap in others

- use steel (which bends) for body construction

- be suitable for towing hauls

- not be ridiculously overpowered (...to the extent where engine can overpower the breaks)

- have good visibility with a windshield that isn't at a sharp angle to the ground and body geometry which doesn't maximize blind spots

- not have sharp corners that the cut you or doors that can decapitate your dog

- have door handles that make doors openable in case of emergencies/no power situations/electric shorts

- not have bulletproof glass (WTF, "for the masses"?) which makes makes it harder to rescue people when accidents happen

- be easily repairable, or at least amenable to repairs in local non-Tesla shops, with customers being confident it their warranty won't go poof (as the law requires)

- be easily customizeable for different applications (particularly when it comes to the bed)

- not look so different from other trucks without any reason other than "Elon Musk wants to be edgy": ugly is subjective, being a billionaire's fashion statement isn't

...to start. That's off the top of my head.

And, of course, being priced for the masses, which doesn't just happen. It's a design requirement.

As it stands, the Cybertruck is, and has always been, a rich boy's luxury toy — and it was designed as one.

It really seems like something got to Musk's head that he thought the world has so many edgy rich boys.

You want to see a modern truck "for the masses"? That's Toyota IMV 0, aka Hilux Champ [1]. Ticks all the above boxes.

And hits the $10,000 price point [2]. A literal order of magnitude cheaper than the Cybertruck.

Speaking of which: a car "for the masses" isn't a truck. It's a minivan (gets the entire family from one place to another), it's a small sedan/hatchback (commuter vehicle), a crossover/small SUV to throw things, kids, and dogs into without having to play 3D Tetris in hard mode.

But not a pickup truck, which is a specialized work vehicle.

The masses aren't farmers and construction workers (most people live in the cities, and only a small number needs such a work vehicle).

The popularity of The Truck in the US is, in a large part, a byproduct of regulation which gives certain exemptions to specialized work vehicles.[3]

That's not even getting to the infrastructure part: trucks shine in remote, rural areas. And while one can always have a canister of gas in the truck bed, power stations can be hard to find in the middle of the field or a remote desert highway.

But again, it's not impossible to make a truck for the masses (at least for certain markets). That's the $10K Hilux Champ.

For all the luxury aspects of the Tesla sedan, it's been one of the most (if not the most) practical electric vehicles on account of range alone. It also looked like a normal car at a time when EVs screamed "look at me, I'm so greeeeeen!" from a mile away (remember 1st gen Nissan Leaf or BMW i3?). It was conformal and utilitarian, while also being futuristic and luxurious enough for the high price point was fair for what was offered.

The public image of having a Tesla was good: you are affluent, future-forward, and caring for the environment.

The Cybertruck went back on everything that made Tesla a success: it's conspicuous, impractical, overpriced, and currently having publicity rivaling that of the recent Melania documentary.

It was not a risky bet. It was an a-priori losing bet. The world simply never needed as many edgy toys as Musk wanted to sell.

And driving a car shaped as an "I'm a Musk fanboy" banner really lost its appeal after a few Roman salutes and the dear leader's DOGE stint.

Overly optimistic engineering assessments? Perhaps, but they are much further down on the list of reasons of Cybertruck's failure.

The actual Cybertruck, once the pre-orders ran out... did not.

Nearly half of all Cybertrucks sold (about 75% of those sold in 2024) were pre-orders.

That's to say, people stopped buying once they saw the Cybertruck for what it actually was (ditto for Elon).

FSD is good in video, given. But its not full self driving as it still requires you to keep an eye on it.

Real FSD for me at least, means I can sit in a 'car' open a laptop and work. But honestly working with a laptop in a car makes it dangerous when driving fast.

For my work commute, I don't need a FSD. For my holiday also not.

What I want is real and save FSD something which has proofen on the road that it is really really good.

We are far away from this. 5 years minimum if not 10. And while Tesla is playing around with FSD and putting it now behind a subscription and fooled everyone with the promise of FSD with HW3 and below, it will not suddenly make Tesla the single leader in FSD at all.

Waymo is working on it, Xpeng can do it, BMW, Mercedes and Nvidia.

For Cybertaxies alone you need a lot of infrastructure (parking spots), cleaning crew, management software etc. you need the legal framework to be allowed to drive them (not going to happen anytime soon in europe) and then you only compete with normal taxis and uber.

torginus 10 hours ago | parent | prev | next [-]

I have an opinion on EVs that basically the only models that make sense are the ones shaped like the 3 and Y.

I feel like EVs are a checkbox product - you either make things 'good enough' for the customer - range, driving dynamics, power, charge speed, smart features, autonomous stuff or don't.

To get range right you need a big battery and low drag and efficiency - the only way you can make the first 2 things in the same vehicle is to create an aerodynamic shape.

This is a packaging problem, you need to make the car low, and long - so you stretch it out, so the battery can be thinner and no longer pushes up the rest of the vehicle. You also have a lot of place in the front for crash structures, and aero shaping. Finally since your car is big (D segment), you can charge more money as per conventions of the market.

If you make a C or B segment car, you either reduce the battery size to save money, which makes it impractical for general use or pack in all that stuff into a smaller volume, and you get a car thats more expensive to make than a Model 3, while having worse drag and range, while the market expects you to charge less for it.

These small cars only make sense with a small battery, but you wouldn't want one for yourself as a second car - hence the robotaxi.

So no, your hypothetical Model 2 would not be cheaper if you didn't compromise it in some major way, which they dont wanna do.

Upwards differentiation is also hard for Tesla - base models are already powerful enough, have all the smart features, they wont compromise on autonomous stuff etc.

This is not only my opinion but the market's - S and X sold like 2 orders of magnitude less cars than the 3 and Y.

ben_w 10 hours ago | parent | next [-]

I think the S and X (and Roadster) sold less because they were expensive early models trying to create a "premium" halo-effect (if so, they succeeded).

For range, how much range is sufficient? This may be one area where the EU and US need fundamentally different vehicles, as per the saying "in America 100 years is a long time, in Europe 100 miles is a long way". Certainly the EU market supports B-segment with 44kWh @ 320 km / 199 miles: https://en.wikipedia.org/wiki/Citroën_C3#Europe_(2024)

SecretDreams 9 hours ago | parent | prev [-]

> This is not only my opinion but the market's - S and X sold like 2 orders of magnitude less cars than the 3 and Y.

They sold less because they're far more expensive and have to compete against much more well put together products. Meanwhile, their platforms are 10 years old and there are now other offerings in an overall niche field.

You're right about aero to an extent, but aero is only felt on long highway drives and it can be mitigated somewhat with a couple more cells. Some consumers will choose style for a cost premium. Others will choose something more expensive simply because they don't want to support Musk.

'cybercab' wouldn't sell well as a 2 seater if it couldn't self drive.

But Tesla's stock price is still stuck in irrational heights, not even remotely justifiable by the company's performance.

It just seems that people reconsider purchasing a physical object way quicker than they reconsider a stock investment. Maybe because the stock investment, especially in TSLA, is considered more like a gamble - "as long as others also think that this stock will skyrocket, even just because they think that others like me think it will skyrocket - as long as that's the case, I'm good with buying shares".

This LIDAR wank annoys me.

If you can train a policy that drives well on cameras, you can get self-driving. If you can't, you're fucked, and no amount of extra sensors will save you.

Self-driving isn't a sensor problem. It always was, is, and always will be an AI problem.

No amount of LIDAR engineering will ever get you a LIDAR that outputs ground truth steering commands. The best you'll ever get is noisy depth estimate speckles that you'll have to massage with, guess what, AI, to get them to do anything of use.

Sensor suite choice is an aside. Camera only 360 coverage? Good enough to move on. The rest of the problem lies with AI.

lateforwork 8 hours ago | parent | next [-]

Even the best AI can't drive without good sensors. Cameras have to guess distance and they fail when there is insufficient contrast, direct sunlight and so on. LiDARs don't have to guess distance.

slfnflctd 6 hours ago | parent [-]

Cameras also fail when weather conditions cake your car in snow and/or mud while you're driving. Actually, from what I just looked up, this is an issue with LiDAR as well. So it seems to me like we don't even have the sensors we need to do this properly yet, unless we can somehow make them all self-cleaning.

It always goes back to my long standing belief that we need dedicated lanes with roadside RFID tags to really make this self driving thing work well enough.

ACCount37 5 hours ago | parent [-]

Nah. That's a common "thought about it for 15 seconds but not 15 minutes" mistake.

Making a car that drives well on arbitrary roads is freakishly hard. Having to adapt every single road in the world before even a single self-driving car can use them? That's a task that makes the previous one look easy.

Learned sensor fusion policy that can compensate for partial sensor degradation, detect severe dropout, and handle both safely? Very hard. Getting the world that can't fix the low tech potholes on every other road to set up and maintain machine specific infrastructure everywhere? A nonstarter.

slfnflctd 5 hours ago | parent [-]

Well, we already provide dedicated lanes for multi-passenger vehicles in many places, nearly all semi-major airports have dedicated lots and lanes for rideshare drivers, many parts of downtown/urban areas have the same things... and it didn't exactly take super long to roll all that out.

Also, 99% of roads in civilized areas have something alongside them already that you can attach RFID tags to. Quite a bit easier than setting up an EV charging station (another significant infrastructure thing which has rolled out pretty quickly). And let's not forget, every major metro area in the world has multi-lane superhighways which didn't even exist at all 50-70 years ago.

Believe me, I've thought about this for a lot more than 15 minutes. Yes, we should improve sensor reliability, absolutely. But it wouldn't hurt to have some kind of backup roadside positioning help, and I don't see how it would be prohibitively expensive. Maybe I am missing something, but I'm gonna need more than your dismissive comment to be convinced of that.

ACCount37 4 hours ago | parent [-]

You are missing the sheer soul-crushing magnitude of the infrastructure problem. You are missing the little inconvenient truth that live in a world full of roads that don't even consistently have asphalt on them. That real life Teslas ship with AI that does vibe-based road lane estimation because real life roads occasionally fail to have any road markings a car AI could see.

Everything about road infrastructure is "cheap to deploy, cheap to maintain". This is your design space: the bare minimum of a "road" that still does its job reasonably well. Gas stations and motels are an aside - they earn money. Not even the road signs pay for themselves.

Now, you propose we design some type of, let's say, a machine only mark that helps self-driving cars work well. They do nothing for human drivers, who are still a road majority. And then you somehow manage to make every country and every single self-driving car vendor to get to agree on the spec, both on paper and in truth.

Alright, let's say we've done that. Why would anyone, then, put those on the road? They're not the bare minimum. And if we wanted to go beyond the bare minimum, we'd plug the potholes, paint the markings and fix the road signs first.

slfnflctd 3 hours ago | parent [-]

You definitely have a point. It would not be rolled out all at once, everywhere. It would happen sporadically, starting with areas that have a higher tax revenue base. There may never be an international standard. There will be tons of places it will never work at all.

All the same, it still reminds me of past infrastructure changes which ended up being widely distributed, with or without standards, from railroads to fiber optic cables.

And this:

> if we wanted to go beyond the bare minimum, we'd plug the potholes, paint the markings and fix the road signs first

...just strikes me as a major logical fallacy. It's like the people who say we shouldn't continue exploring our solar system because we have too many problems on Earth. We will always have problems here, from people starving because of oppressive and unaccountable hierarchies they're stuck under to potholes and road markings the local government is too broke or incompetent to fix. We should work on those, yeah, but we should also be furthering the research and development of technology from every angle we realistically can. It feels weird to be explaining this here.

And as long as those places dominate, it makes more sense for AI car makers to say "let's put $5m more into raw dog vision only FSD AI" than it does to say "let's add a $25 long range RFID reader to every car". No one will bet their future on "the infrastructure for it will maybe one day exist".

Just look at how Waymo is struggling to grow and scale. And they don't even need every road remade. They just need every road mapped and scanned out into 3D objects with their reference cars. They're solving a problem orders of magnitude easier, and it still throttles their growth.

Are they? They seem to be growing fine.

Regardless, they are approaching it the right way. They start with a safe solution, even though it is expensive, then bring the cost down over the years as technology improves. The wrong way to do it is to start with a less expensive but unsafe tech then add a safety driver in every car. That approach is wrong both because the "tech" of the safety driver will never improve, and you'll kill a few people along the way, like Tesla.

What do you believe the frame rate and resolution of Tesla cameras are? If a human can tell the difference between two virtual reality displays, one with a frame rate of 36hz and a per eye resolution of 1448x1876, and another display with numerically greater values, then the cameras that Tesla uses for self driving are inferior to human eyes. The human eye typically has a resolution from 5 to 15 megapixels in the fovea, and the current, highest definition automotive cameras that Tesla uses just about clears 5 megapixels across the entire field of view. By your criterion, the cameras that Tesla uses today are never high definition. I can physically saccade my eyes by a millimeter here or there and see something that their cameras would never be able to resolve.

Edman274 3 hours ago | parent [-]

I can't figure out your position, then. You were saying that human eyes suck and are inferior compared to sensors because human eyes require interpretation by a human brain. You're also saying that if self driving isn't possible with only camera sensors, then no amount of extra sensors will make up for the deficiency.

This came from a side conversation with other parties where one noted that driving is possible with only human eyes, another person said that human eyes are superior to cameras, you disagreed, and then when you're told that the only company which is approaching self driving with cameras alone has cameras with worse visual resolution and worse temporal resolution than human eyes, you're saying you respect the grind because the cameras require processing by a computer.

If I understand correctly, you believe:

1. Driving should be possible with vision alone, because human eyes can do it, and human eyes are inferior to camera sensors and require post processing, so obviously with superior sensors it must be possible 2. Even if one knows that current automotive camera sensors are not actually superior to human eyes and also require post processing, then that just means that camera-only approaches are the only way forward and you "respect the grind" of a single company trying to make it work.

Is that correct? Okay, maybe that's understandable, but it makes me confused because 1 and 2 contradict each other. Help me out here.

My position is: sensors aren't the blocker, AI is the blocker.

Tesla put together a sensor suite that's amenable to AI techniques and gives them good enough performance. Then they moved on to getting better FSD hardware and rolling out newer versions of AI models.

Tesla gets it. They located the hard problem and put themselves on the hard problem. LIDAR wankers don't get it. They point at the easy problem and say "THIS IS WHY TESLA IS BAD, SEE?"

Outperforming humans in the sensing dept wasn't "hard" for over a decade now. You can play with sensors all day long and watch real world driving performance vary by a measurement error. Because "sensors" was never where the issue was.

There's not really NEV oversupply, the EV adoption curve will keep shooting up from 50% to 100%, many PRC EV companies will die from competition/pricewar consolidation not broader oversupply, since EV industrial base is still undersupply relative to 100% adoption curve.

Oversupply is in legacy ICE displacement due to rapid domestic EV penetration. "Zero-milage used car" accounting trick is primarily to export excess capacity of gasoline cars (now that EV has taken over) that aren't moving domestically anymore. MOST of PRC exports are ICE, IIRC 60-80%, there's plenty of global demand for ICE still. Pushing domestic sku new car with crushed domestic demand as "used" exports where there's plenty of demand = meet sales target, but less through discounts but import fees engineering - used cars circumvent import duties, certifications, warranty requirements etc. It's a lifehack to unload domestic ICE inventory, not EV. This also likely transient effect because NEV transition in PRC happened so fast ICE manufacturer that target domestic market caught flat footed. They need a few years to either retool to EV or shift primarily to target export markets that still has appetite for affordable gasoline cars.

The Reuters article focuses on exports because that's what their target audience is likely to be interested in, but the People's Daily article they reference in passing https://paper.people.com.cn/rmrb/pc/content/202506/10/conten... is treating it as a domestic problem, highlighting the appearance of "zero-mileage used cars" on the second-hand market, specifically calls out EV companies for putting quantity over quality, and floats stimulating used car exports as part of the solution.

Also, at least the EU doesn't distinguish between new and old cars when importing from outside the EU https://taxation-customs.ec.europa.eu/buying-and-selling-car... presumably precisely to avoid creating the kind of loophole you imagine exporters are exploiting. But they aren't; they just hurt their own profitability to juice their numbers and chase growth.

maxglute 11 minutes ago | parent [-]

Domestic problem as in domestic involution problem not a EV overcapacity problem. I'm pointing out important to distinguish between ICE and EV, ICE is structural overcapacity, EV is under capacity but involution. ICE zero mile shenanigans is to liquidate/ unload excess inventory that doesn't have demand in PRC, mostly targeting loopholes in russia, central asia, mena. There's (less regulates) markets other than EU.

BYD/EV zero mile hack is more for subsidy harvesting, they're trying to dip on domestic subsidies for new sales then skip on stuff like servicing/warranty because used sale, i.e. shady involution behavior that abuse national policies, hence crackdown. It's not because EV are excess capacity, but so many EV players involuting and accountants find creative ways to carve margin. It's not EV sector makes 100 cars can only sell 50, because overcapacity, so discount to sell 100. It's EV sector makes 100 cars, sell 100 @1% margin but with some engineering they sell 100 @2% margin.

Yes, there are some brands that does use it for price cuts, premium brands, i.e. nio/xpeng, who won't lower sticker price, so they have to flip to lower price in used market. But that's also less overcapacity, more PRC EV moving so fast last few years no one wants 12 month old models. AKA tech stack progressing so fast / involution pressures so hard consumers won't pay sticker for anything older than 1 gen. What happens PRC manufacturing turns car cycles into phones obsolescence cycles. The broader the point here is EV makers are generally not doing accounting tricks to sell more cars due overcapacity / lack of demand (what over capacity implies), they're doing accounting tricks to sell the same amount of cars to make their razer thin involution margins slightly less razer thin, at the expense of the government.

I'm not sure I agree. I think just having wings that flex a bit is mechanically simpler than having an additional rotating propellor. After all, rotating axles are so hard to evolve they never almost never show up in nature at a macro scale. Sort of a perfect analogy to lidar actually. We create a new approach to solve the problem in a more efficient way, that evolution couldn't reach in billions of years

adrian_b 11 hours ago | parent [-]

Rotating axles have not evolved in animals not because they were complex, but because any part of an animal requires permanent connections with the other parts, not only for the supply with energy but also for the continuous repairing that is required by any living body, to avoid death.

Artificial machines rely on spare parts manufactured elsewhere, which are used by external agents to replace the worn out parts.

For an animal to have wheels, it would have to grow wheels in some part of the body, periodically, then use its limbs to detach the wheels and attach them on the axles, after removing the old wheels. This is something sufficiently complex to be extremely unlikely to appear from evolution.

Even this huge complication would be enough only for passive wheels. For active wheels there exists no suitable motor, as the rotational motors with ionic currents are suitable only for the size of a bacteria. All bigger living beings use contractile motors, which cannot be used for a rotation of unlimited angle. So active wheels would also need a different kind of motor, which can work without a solid connection between the 2 moving parts. The artificial motors of this kind use either electromagnetic forces or fluid expansion due to temperature or pressure variation. Both would be very difficult to evolve by a living being, though electric fish and bombardier beetles show some possible paths.

tinix 8 hours ago | parent [-]

Living beings are not devoid of axles and wheels; rather, they are entirely composed of them, at scales and in forms compatible with biology.

At every relevant level, life relies on rotating and cyclic structures coupled through continuous material exchange. The objection to wheels in animals assumes that axles and wheels must be rigid, permanently isolated parts. Biology does not work this way. Instead of discrete components joined once and preserved unchanged, living systems implement rotation through structures that are simultaneously connected, repaired, and replaced.

Cells are full of rotary and quasi-rotary machinery. Flagella are true rotating motors with stators, rotors, bearings, and torque generation via ion gradients. ATP synthase is literally a wheel-and-axle device, converting rotational motion into chemical energy and back again. The fact that these devices operate at molecular scale does not make them conceptually different from macroscopic axles; it shows that evolution favors rotation precisely where continuous repair and material flow are required.

At larger scales, joints function as constrained rotational interfaces. Hips, shoulders, knees, and vertebrae are axles embedded in living bearings, lubricated, rebuilt, and reshaped throughout life. Bone remodeling, cartilage regeneration, and synovial fluid circulation solve the very problem claimed to prohibit wheels: permanent connection combined with continuous maintenance. The difference from artificial machines is not the absence of rotation, but the absence of rigid separability.

Even limbs themselves behave as compound wheels. Gait cycles convert linear muscle contraction into rotational motion around joints, then back into translation. Tendons wrap around bones as belts around pulleys. Muscles do not rotate indefinitely, but unlimited rotation is not a requirement for a wheel; it is a requirement imposed by certain human machines. Biological wheels rotate as much as function demands, then reverse, exactly as many engineered systems do.

The claim that active wheels require exotic motors overlooks that biology already uses fields and flows. Ionic gradients are electric fields. Blood pressure, osmotic pressure, and gas expansion are fluid-based actuators. Electric fish demonstrate macroscopic bioelectric control, and insect flight shows that indirect actuation can drive cyclic motion far from the muscle itself. The distinction between electromagnetic motors and biological motors is one of implementation, not principle.

What evolution did not produce is a detachable, externally replaceable wheel, because life does not outsource maintenance. Instead, it internalizes repair, redundancy, and gradual replacement. From this perspective, an animal is not a wheeled vehicle lacking wheels; it is a dense hierarchy of axles and wheels whose boundaries are soft, whose materials are alive, and whose motion is inseparable from their growth and repair.

Life did not fail to invent wheels. It dissolved them into itself.

adrian_b 7 hours ago | parent [-]

Most of what you have said is not different from what I have said.

All the rotating parts bigger than some tens of micrometers have only a limited rotation angle, where the limits are enforced by the solid connections between the 2 mobile parts, e.g. tendons, nerves and blood vessels.

The bacterial flagella and the rotating enzymes, which are powered by ionic currents, cannot be scaled to greater sizes. Already the flagella of nucleated cells (eukaryotes) are no longer based on rotating motors, but on contractile proteins, which must be attached at both ends on the mobile parts, limiting the relative movement.

Unlimited rotation is an absolutely necessary condition for a wheel that is used in locomotion, otherwise it is no longer a wheel.

A wheel used in locomotion that would have limited rotation would be just a leg that happens to have the shape of a wheel, because like a leg it would have to be raised from the ground for the forward motion, eliminating the exact advantage in efficiency that wheeled vehicles and tracked vehicles have over legs (i.e. that backward and forward movement are simultaneous and not separated in time during a step cycle, and no energy is wasted with a vertical oscillation of the leg).

The distinction between electromagnetic motors and biological motors is definitely one of principle and not an implementation detail. The only resemblance is that both are motors.

It is true that you can claim that when analyzing both chemical reactions and the interactions between the mobile parts of an electromagnetic motor they can be eventually reduced to electromagnetic interactions. Nevertheless such an assertion is completely useless, because most things that matter to us in the surrounding world can be reduced to electromagnetic interactions. Knowing this is not helpful at all for classifying them and understanding the differences between them.

The contraction of a protein caused by a chemical transformation and the magnetic forces that appear either between electrical currents through conductors or between electrical currents and ferromagnetic materials are very different phenomena and knowing that both of them have as primary cause electromagnetic interactions is of absolutely no help for understanding how they work or for designing either kind of motors.

Electromagnetic motors that are not extremely small need ferromagnetic materials. The only ferromagnetic material that is known to be synthesized by living beings is magnetite. Magnetite crystals can be good enough for sensing the magnetic field of the Earth, but they would be a very poor material for motors.

An easier to evolve rotating biological motor would be a rotating hydraulic motor, e.g. powered by pumped blood or lymph. This could work if the wheel would become non-living after being grown, to no longer need nerves and blood vessels. However it would be very difficult for a living being to seal the space between an axis and the rotating wheel in such a way so that blood or lymph would not spill out through the interstice.

Others in this subthread discussed the comparison of the complexity of different ways of achieving flight itself, but I think there is an interesting discussion in that... well... we do add senses we don't technically need to achieve stable flight (but are very useful for safe flight and have reduced the incidence of aviation incidents and accidents dramatically).

Whether it be altimeters based on radio[1] or air pressure[2], avoidance and surveillance systems that use radio waves to avoid collisions with other aircraft[3][4], airborne weather radars[5], sensors that measure angle of attack (AoA), GNSS location, attitude, etc, many aircraft (even unpowered gliders!) have some combination of special sensing systems that aren't strictly necessary to take off, fly to a destination, and land, even if some are required for what many would consider safe flight in some scenarios.

Many of these systems have redundancies built in in some form or another and many of these systems are even built into unmanned aerial systems (UASes) big and small.

Human eyes do have greater dynamic range in the visible light spectrum, but solid state sensors can commonly interpret light above 1000nm, and of course you can do thermal/IR imagers to provide optical sensing of wavelengths outside of what a human can see.

Sensor technology relative to the human eye isn't what is holding FSD back.

Technology can't compete with how easy it is to make more human-based navigation devices ;-)

Humans have cameras (eyes) + AGI. Cars have to compensate with LiDARs and other sensors that humans don't.

This is commonly said but trivially falsifiable — a blind human crosses the street better than a Tesla.

Eyesight isn’t the thing. Humans have a persistent mental model of the world, and of the physics that drive it. Our eyes only check in every now and then to keep our model up to date.

Our ears and sense of touch do a lot of work in walking and driving, too. Trying to narrow it all down to vision is silly.

Deaf people drive.

I knew a guy with no arms who drove with his prosthetic hooks. Of course he can feel vibrations and things through his ass, but so could the car if they wanted. Do they use accelerometer data? (I don't know the answer to that) Do they have ABS sensors that can detect wheel lockup/speed status? Because I don't.

I believe I can drive a car to the legal standard, remotely, with a good enough camera array.

You might be able to but again, that has little to do with vision and much to do with your persistent and correct mental model of the world.

We don’t drive with just our eyes, we also drive with our brains.

Careful now. You'll get branded as a "Tesla hater" for stating facts like that. Or you'll get unflattering ad-homs comparing you to the Electrek guy
