I'm renting a Tesla Model Y with HW4 and FSD version 14.2.2.5 to see for myself what it's like and how plausible it is that vision-only level 4 self-driving is imminent.

If I disengage the self-driving but it's ambiguous if I actually needed to, I'll resolve-to-PROB appropriately. In other words, we're estimating the probability of a would-be crash of any severity over 2000 miles of self-driving, almost all highway miles.
