I suspect if you crunch the numbers, accidents are going to be above normal for a while after Covid-19 reopenings.
Anecdotally, I'm seeing people doing mind-blowingly stupid things on the roadways right now. It seems like people have forgotten how to drive. I suspect the issue is that people rely too much on other cars to cue them how to behave and the concentration is too low.
(It could also be that a constant accident rate cleans off the worst of the drivers with regularity as they get into accidents and then wind up out of circulation. I really hope that isn't why ... that would be really depressing.)
And we know we shouldn't drive tired or angry or intoxicated but obviously it still happens.
As soon as you get experience-sharing - culture, as humans call it, but updateable in real time as fast as data networks allow - you can build an AI mesh that is aware of local driving conditions and learns all the specific local "map" features it experiences. And then generalises from those.
So instead of point-and-hope rule inference you get local learning of global invariants, modified by specific local exceptions which change in real time.
