Yes thank you. I was literally thinking "the worst driver I know has been in two accidents in the 20 years of our friendship, that must be pretty close to 99.9% safe."

I don't have very strong intuition about risks this small. I do know the thing that ultimately lead me to being able to beat nethack at will was internalizing the idea that "something that's 99% safe is almost certain to kill you over the course of a run." Feels similar.
