I think you're humongously overselling the average driver. I mean, the stats for waymo vs human drivers speak for themselves.
In Houston the stats suggest that every driver should get into a crash at least once every. But many ppl haven’t been an crash all their lives and more have been in multiple
Depends on how you define "average driver": what if 95% of the crashes are caused by 5% of the drivers?
My reading of all the human crash stats has been that majority of them happen when human drivers are impaired (drunk, drugged or too tired): as this is something we could (in theory, at least) control, I'd like to see and compare with stats for non-impaired human drivers too.
Then, I'd like to see it compared to attentive, non-distracted drivers too (but we won't have crash data for this, as they would avoid most potential crashes).
Note that I am only talking things under every human driver's control, and not things like skill, reaction time, etc.
Also, modern cars (like Waymos) will have a much lower braking distance compared to "average": eg. my Volvo has 35m braking distance from 100km/h or 62mph compared to 50m (45% more) listed as average (excluding reaction distance) — so from 50km/h, it should be around 8m!
