In addition to the confounding variables others have mentioned, I think the most important factor is when autopilot is enabled. If you don't (or can't) use autopilot at night, in inclement weather, or in construction zones, then you'll get into more accidents when not using autopilot -- even if it's a significantly worse driver than you are.

not so fast. youneed to compare tesla death per mile withother high end sedan death per mile. comparing a population of all cars include a lot of less secure cars, like city cars, old cars and cars that haven't enjoyed the same level of maintenance a driver with high income can afford.

iow tesla needs to beat the average 2014+ 3 series death per mile.

You also need to account for the regions where Teslas are most popular, the demographic of people who are purchasing Teslas, cars with similar safety features, and many other factors. Comparing the very tiny slice of the market which drives Teslas against every other car+driver on the road is almost meaningless.
