A) accidents per driven mile and B) probability of injury in an accident

in terms of crashes per mile, nhtsa reported waymo having the most total crashes last year of any automated driving system.
https://www.nhtsa.gov/sites/nhtsa.gov/files/2022-06/ADS-SGO-...
waymo had 62 crashes in 2.3 million miles driven which is 1 crash per 37K miles, compared to autopilot 1 crash per 4.31M miles or 1 crash per 1.9M miles with a human driving (plus emergency safety features included free in every vehicle).
so the average autopilot vehicle instance travels ~2 full waymo fleet years of driving before crashing once, rather than crashing 124 times.
