> Then you go to list all the problems with just the car. And your problem is putting your own AI on a car to self-drive.(Linux isn't AI btw).

It's not just about AI driving. I don't want anyone's shoddy and not signed-off crap on the roads - and Europe/Germany does a reasonably well job at that: it is possible to build your own car or (heavily) modify an existing one, but as soon as whatever you do touches anything safety-critical, an expert must sign-off on it that it is road-worthy.

> What about putting your own linux on the multi-media interface of the car?

The problem is, with modern cars it's not "just" a multimedia interface like a car radio - these things are also the interface for critical elements like windshield wipers. I don't care if your homemade Netflix screen craps out while you're driving, but I do not want to be the one your car crashes into because your homemade HMI refused to activate the wipers.

> What about a CPAP machine? heart monitor?

Absolutely no homebrew/aftermarket stuff, if you allow that you will get quacks and frauds that are perfectly fine exploiting gullible idiots. The medical DIY community is also something that I don't particularly like very much - on one side, established manufacturers love to rip off people (particularly in hearing aids), but on the other side, with stuff like glucose pumps actual human lives are at stake. Make one tiny mistake and you get a Therac.

> Microwave?

I don't get why anyone would want Linux on their microwave in the first place, but again, from my perspective only certified and unmodified appliances should be operated. Microwaves are dangerous if modified.

Lets invent circumstances where it would be a problem to run your own car, but lets not invent circumstances where we can allow home brew MMI interfaces. Such as 99% of cars where the MMI interface has nothing to do with wipers. Furthermore, you drive on the road every day with people who have shitty wipers, that barely work, or who don't run their wipers 'fast enough' to effectively clear their windsheild. Is there a enforced speed?

And my CPAP machine, my blood pressure monitor, my scale, my O2 monitor (I stocked up during covid), all have some sort of external web interface that call home to proprietary places, which I trust I am in control of. I'd love to flash my own software onto those, put them all in one place, under my control. Where I can have my own logging without fearing my records are accessible via some fly-by-night 3rd party company that may be selling or leaking data.

I bet you think that Microwaves, stoves etc should never have web interfaces? Well, if you are disabled, say you have low vision and/or blind, microwaves, modern toasters, and other home appliances are extremely difficult or impossible to operate. If you are skeptical, I would love for you to have been next to me when I was demoing the "Alexa powered Microwave" to people who are blind.

There are a lot of a11y university programs hacking these and providing a central UX for home appliances for people with cognitive and vision disabilities.

But please, lets just wait until we're allowed to use them.
