IDK, I've been in the car with someone when they just up and up drove off the road because they failed to notice that there was a corner - and that's a sober human. Another time, someone else, they rounded a corner, saw a tractor in the other lane, and were so surprised that they hit a tree. My mother has totalled six cars - she insists it was someone else's fault every time, but the statistics are somewhat damning. My wife's driving has given me haemmorhoids, I clench so fucking hard. Blind corners at twice the speed limit, looks over her shoulder to talk to passengers, and I constantly find myself buying wing mirrors, fenders, headlights, body panels, hubcaps, and anything else she can break off on traffic, rocks, or street furniture. Well, I did until someone finally took her license away from her for a year.

So... not so sure. Every AV I've ever been in has driven incredibly cautiously compared to a human driver.
