The average person is way better at driving cars if you define it properly, and not in an unfair, biased way that is used to hype up teslas.

It is almost trivial to drive on a highway and since you are driving faster accidents/miles is just gonna be low. Even just by not getting tired and having a fancy smart vacuum logic it might provide better results. But they are absolutely bad at regular traffic with millions of events, variable environments, etc. Where people will turn off their gimmick feature and self-select against the hard cases.
