There is about 36000 death on the road per year in the USA for 280 millions vehicles, that's 128.5 death/million vehicule/year
If we assume the number of tesla autopilot death double this year to 8 (from 4 at the time of probe launch), for about 900 thousand tesla on the road in USA, that's 8.9 autopilot death/million tesla/year.
Ratio between the numbers of 14.4.
Tesla reporting says for Q1 2021 one crash on autopilot per 4.19 millions miles vs one crash per 484 thousand miles all vehicules.
Ratio between the numbers of 8.7
All numbers are full of biases and their ratio probably aren't that meaningful but they end up in the same magnitude.
Interesting data there "Fatality Facts 2019 Urban/rural comparison":
https://www.iihs.org/topics/fatality-statistics/detail/urban...
"Although 19 percent of people in the U.S. live in rural areas and 30 percent of the vehicle miles traveled occur in rural areas, almost half of crash deaths occur there. "
I was shocked that in the USA in 2019 about 40-46% of all road death people were unbelted, while 90% of front seat people wear seat belts according to observation studies.
Incidentally tesla car will beep to no end if weight is detected on a seat and seat belt isn't clicked: I have to click the seat belt when I put my (not so heavy) bag on the passenger seat since there's no software option to disable the beeping.
