On top of that, aviation autopilots operate in one of the most controlled and stable environments. Ground based individual traffic is the polar opposite of that.
As aviation people eloquently put it: https://en.wikipedia.org/wiki/Big_sky_theory I think there should be a correlative 'small road theory', if only to underscore the difference.
Except the general public seem to massively over-estimate how capable aircraft Autopilots are, and then expect Tesla's Autopilot to live up to their inflated expectations.
the general public doesn't fly planes, so to them every flight is getting on a plane, falling asleep, and magically teleporting from one city to another. They have no perspective on just how much an autopilot doesn't do.
