Yes and there's also a kind of lying with statistics that goes on. That human accident rate includes drunk drivers, very young drivers, very old drivers, etc.
The average accident rate is not your expected accident rate, if you are an average person who is not in those categories.
We don’t know yet what the acceptance rate is for autonomous accidents - but I can guarantee it’s not the rational value of 1:1 or “as safe as humans”. They’ll need to do a lot better.
