I wish all of these benchmarks pitted autonomous cars against a somewhat comparable user group – say professional taxi drivers – over just a general sampling of the population. The majority of people are driving most of their miles during rush hour when chances of a crash are the highest, while Waymo cars operate all day/night. Plus I'm sure that first-time drivers, drunk drivers, people out on illegal joyrides and other such extremes drag the numbers down enough that saying "I'm in the top 40%" really isn't all that meaningful anymore.
What I'm interested in knowing is how these cars drive compared to the average competent driver in the exact same environment.
