The real problem is that roads are vastly unconstrained systems. An analogy is you can't take a sieve and fill all the holes in it with AI because it has no determinism and you don't know what all the constraints/holes are in the first place. Humans can actually reason in these situations fairly competently, even the stupid ones.
Give up, produce a half decent low price car with basic features that a human drives that frees us from the insane EV pricing jump and perhaps the world will be changed. Self driving cars are not important other than for a few exec egos and companies who want rid of the cost of a human workforce.
This is another fucking race to the bottom and the only innovation is getting people to think it's important.
