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!

To be fair, if 5% of drivers cause 95% of crashes then the average driver is still terrible.

The median one might be better, but does it even matter? The average driver is still wreaking havoc.
