So % of sold cars that end up in fatal crashes:

Tesla: 0.0322% (or 1 in about 3100 cars sold)

Ford: 0.8836% (or 1 in about 114 cars sold)

Its late for me, so check my math, but I think it’s right.

That looks about like you took the 2020 fatal collisions and divided by the 2019 sales, but that doesn't make a whole lot of sense. Probably most of the Ford crashes were not from the 2019 model year, they've been selling cars for over a century, and many of their cars are still on the road.

My understanding is fatal crashes are biased towards older models as well. Tesla has barely any cars over 10 years old, let alone 20 or 40 or 50.

More fair would be to look up registered vehicles by make and compare to fatal collisions (which I can't find a free source for, unfortunately).
