| It’s a remote controlled CO2 canister on wheels with a skin that looks like a car. It’s a stupid publicity “stunt”. Har har Elon. |

| I know its marketing but still it's super inspiring to me. Try pulling it off in real hardware. It's incredible. |

| Can't wait for these things to endanger my family's life on some Colorado mountain highways. If the suction works at speed, people are gonna drive even more recklessly. |
| |
| ▲ | lern_too_spel 25 minutes ago | parent | next [-] | | The suction can only work on a cleaned track. On a standard public road, they have to deal with capturing and disposing debris. | |
| ▲ | laimewhisps 32 minutes ago | parent | prev [-] | | Thankfully this will never hit the road, it's just market manipulation. | | |
| ▲ | talon8635 25 minutes ago | parent [-] | | What do you mean “just market manipulation”? There’s no engineering advancement here? I sure hope they don’t hit the road. Seems like an obviously novel (and terrifying) consumer technology | | |
| ▲ | Betelbuddy 5 minutes ago | parent | next [-] | | >> There’s no engineering advancement here? No advance. Its engineering gimmicks to hide the fact self driving is 15 years late, and all recently announced Tesla models are worst, and more expensive, than any Chinese alternative. | |
| ▲ | sottol 11 minutes ago | parent | prev | next [-] | | You did say "consumer tech" - so you're probablt aware of the BT-46. But this has been done a few times before... though it's probably more dangerous than ever with up to 1MW (1000kW) output from electric motors. Some of these were actually sold afair. I'm not sure about those thrusters though, I doubt they'd be legal?

| ▲ | kelseyfrog 11 minutes ago | parent | prev | next [-] | | Tesla has a history of failed hype campaigns. At this point, them hyping something is a negative expectation that it will come to pass. | |
| ▲ | lern_too_spel 13 minutes ago | parent | prev | next [-] | | The jumping car used a 600L canister of 10 kPSI compressed air behind the seats. Musk claimed the car will be able to refill the canister itself, but he didn't demonstrate that. In reality, the size of a multistage compressor to reach those pressures and the heat dissipation for compressing air to 680 atmospheres makes that impractical. You would have to get filled up at whatever specialized system they used for the demo. | |
| ▲ | laimewhisps 11 minutes ago | parent | prev [-] | | I mean it will never be a product. It's just story telling to try and justify the premium Space X is about to pay to acquire Twitter, I mean Tesla. |

| If Doc Brown's time machine was real and posted here, HN would be complaining that it's noisy, unimpressive, not street legal, uninsurable, and attacking Brown's personal character because he's a dangerous nutcase. |

| I genuinely didn't believe they'd ever do more than use cold gas thrusters for a lame boost effect, if at all. Happy to admit I was wrong, that was cool. (still not buying a tesla thooughbeit) |

| If used on public streets, these thrusters could easily maim/kill people- reckless to include them on a car. |
| |
| ▲ | Maxatar 44 minutes ago | parent | next [-] | | The one with the actual rocket engine is not being sold to the public and Tesla website explicitly states it's not legal to drive it on public roads. It's mostly just a cool demo/prototype and I'm sure there will be privately run tracks that let people drive one. The generally available car will have cold-gas thrusters which boost acceleration but is nothing like what was demo'd. | | |
| ▲ | laimewhisps 38 minutes ago | parent [-] | | It's mostly just stock fraud and laying the way for the Space X acquisition of Tesla at a hyper inflated valuation. |
| |
| ▲ | 827a 40 minutes ago | parent | prev | next [-] | | Teslas already have very strict (annoyingly strict) gating keeping specific functionality off of public roads (Summon). The drag mode thruster-assisted boost will probably leverage that. I also imagine that cameras on the car would stop it from being engaged if it detects humans in its firing area even when not on public roads. The flying trim will never be sold to general consumers. Even the rear-thruster trim is currently listed at a $250,000 pre-order fee, which is a deposit for a fraction of the full cost of the car. Final cost will be over $1M. Any of the thruster variants will be extremely rare; like, the one guy in your city that has one will show it off at car shows twice a year, McLaren P1, level of rare. | | |
| ▲ | oslem 31 minutes ago | parent | next [-] | | In a video by Hagerty’s, Tesla claimed that both variants will be sold, for whatever that’s worth. | | |
| ▲ | 827a 19 minutes ago | parent [-] | | Yeah they'll make a few dozen of them and sell them to people like Joe Rogan. There is zero chance that any individual who doesn't have the personal phone number of a Tesla leadership team member will be able to buy one of these. |
| |
| ▲ | 7e 35 minutes ago | parent | prev [-] | | So it's a car for wankers. Makes sense. |
| |
| ▲ | SketchySeaBeast 39 minutes ago | parent | prev | next [-] | | And it's sure going to increase the blast radius when these get into a collision. Even if you can't fire the thrusters, that pressurized tank can't be safe. | |
| ▲ | tyleo an hour ago | parent | prev [-] | | I’m no Musk fan but I found it cool and try to balance my negativity towards the person with what I’m seeing. Plenty of ways to maim/kill people in traditional cars already and I doubt this will be the most common one in roadsters. |

| The reality of EVs is that they all provide more or less identical driving experience - immense amounts of speed in straight lines and pure control around corners. But you can't really make something nimble or chuckable when it weighs 1.5 tons. (Calling it a "roadster" is cute, but this has nothing in common with a Boxster or Miata. If anything, the ICE analogue would be muscle cars.) Because there are no real unique driving characteristics, the only engineering you can compete with is raw speed or price. That and crazy gimmicks. |
| |
| ▲ | jandrese 17 minutes ago | parent | next [-] | | This thing is covered in cold gas thrusters, I'm betting it can go around a corner faster than almost any other car. The limitation might be G forces on the driver. Maximum performance may only be achievable in self driving mode. | |
| ▲ | simonebrunozzi 25 minutes ago | parent | prev | next [-] | | > when it weighs 1.5 tons. Are you referring to the Tesla Roadster? Because, if not, I am pretty sure that most EVs, except for maybe small compact EV cars, usually weights 2 tons or more. | | |
| ▲ | maxdo 18 minutes ago | parent [-] | | tesla roadster weights 1.6-1.7 tons, thats prob without compressed air. But common, if you buy a rocket car, that is capable to suck itself to the road, you will not care about this extra 300-400 kg of weight, that probably will be compensated by perfect low center of gravity and several motors. |
| |
| ▲ | maxdo 23 minutes ago | parent | prev [-] | | yes, you can, if you think like an engineer.
they have suction mechanism, low center of gravity that helps you to beat any ICE counterparts. You can't call this beauty of engineering a muscle car. |

| Am I missing something? At what point did the car fly? The thrusters were able to cushion a fall. That seems useful in ruining the ending of Thelma and Louise, but isn’t really a flying car. |
| |
| ▲ | kuerbel 28 minutes ago | parent | next [-] | | There is a video where it is flying over some other Teslas. Actually taking off, barrel roll and landing | |
| ▲ | guax 12 minutes ago | parent | prev | next [-] | | It flies the same as a chicken. Cushion and long jumps but not flying as in flying car or plane. | | | |
| ▲ | jandrese 15 minutes ago | parent | prev | next [-] | | "It's not flying, it's falling with style!" I think this is pretty unique demonstration for something that theoretically may be street legal one day. | |
| ▲ | figers 28 minutes ago | parent | prev | next [-] | | yes it cushioned the fall, but not sure if it was overly modified beyond realistic car weight for production / public. | |
| ▲ | FergusArgyll 12 minutes ago | parent | prev [-] | | Yes, you missed the middle of the video. |

| This seems less like a consumer product than a stock market demonstration of the supposed synergies of merging SpaceX and Tesla. |

| Why Musk would spend probably tens of millions of dollars on this prototype which clearly will never be drivable on roads. One explanation is he is a trillionaire and the 14 year old in him thinks it would simply be cool to do it. I think there is a more rational explanation. Tesla sales have slowed, other companies are catching up, and if it weren't for import issues, Chinese cars would be eating Tesla's breakfast, lunch and dinner. Yet Tesla is trading at a 330 P/E and Musk has to do something to make it seem like Tesla is still light-years ahead of everyone else and just wait, that 330 P/E will be justified any quarter now. Just like shooting a roadster into deep space was just a PR stunt, this is a PR stunt to boost the brand with no actual market relevance. |
| |
| ▲ | dkenyser 20 minutes ago | parent | next [-] | | > other companies are catching up Catching up? BYD has already surpassed Tesla and looks like the gap is going to continue to grow. | |
| ▲ | laimewhisps 33 minutes ago | parent | prev | next [-] | | Absolutely, but an even more likely explanation is that he's going to "acquire" Tesla with Space X and pay a premium (on top of the 330 P/E!). The SEC in this country is completely useless. Sure you can't invest in private companies if you're not an "accredited investor" but Musk is free to scam trillions of dollars. | |
| ▲ | antonvs 24 minutes ago | parent | prev [-] | | > One explanation is he is a trillionaire and the 14 year old in him At this point it's not clear that there's anything other than a 14 year old in him. A greedy, sociopathic 14 year old. |

| FSD doesn't even work properly TEN YEARS after it was announced still tries to murder passengers jumping across traffic at shadows good luck with anything Musk, you are the beta tester, if you die they'll debug it, eventually |
| |
| ▲ | 827a 31 minutes ago | parent [-] | | If you still believe FSD doesn't work, you're operating on outdated intelligence. Frankly, like a boomer saying that email doesn't work. | | |
| ▲ | jandrese 13 minutes ago | parent [-] | | Oh, it doesn't require a person to continually monitor it now? I missed that change. Until that happens I don't think it qualifies as "full" self driving. | | |
| ▲ | 827a 3 minutes ago | parent [-] | | Only from a regulatory perspective. Anyone who drives a Tesla for long enough knows how to defeat the monitoring system, and doing so is extremely safe; significantly safer than a human driver. I would have no concerns summoning it autonomously over 100 miles, once the law allows for that to happen. |

| Musk really is the master of fraud. Twitter gets bought by Space X to conceal the massive loss in valuation, Tesla gets pumped with endless "we'll have self-driving cars next year", for 10+ years... now that the Tesla bubble is finally popping he needs to dump it on the Space X/Twitter shareholders, so we get this demo of a thing that will never hit the road. Bag holders beware, Musk's masterpiece of market manipulation is about to execute with the merger of all his lies. |
| |
| ▲ | bigtunacan 28 minutes ago | parent [-] | | Twitter wasn’t bought to conceal the loss in valuation. It was bought so Elon can influence the populace with his narrative. | | |
| ▲ | dingaling 13 minutes ago | parent [-] | | No, he bought it because he was contractually obliged to do so even after he tried to wriggle out of it. I mean this isn't even ancient history, it only happened in 2022. He sent three termination notifications before it was determined that he had no grounds to refuse to buy. |

| After Elon almost died in 2000 when he lost control of his McClaren I wonder if the real reason for these thrusters isn't actually to recover when controlling this beast proves too much for the driver and it starts to spin out or accidentally launches into the air. |
