I've noticed a lot of automation legally still require a warm body to take the blame. Seems like eating your cake and having it too.
Waymo are driving, there is no warm body, in accidents where a Waymo self driving taxi struck somebody that's on Waymo, you're just a passenger the same as if you were in a New York cab, or a Uber, or if an A320 you're sat in smacks into a post because the pilots took a corner too close. You're not the one who needs insurance, because you're not driving, Waymo is.
Even Waymo still has some safety drivers per the article linked. And if we are going to constrain our analysis to self driving pilot programs, then we need to constrain the comparison to the same geofenced area. Arguably there are not a lot of fatal accidents per 1M miles on the local roads of Phoenix/SanFran by human drivers either.
I raise this because the pool of people buying a Tesla is different than the full driver pool. There is likely serious sampling bias in this pool of drivers due to demographics, geographics, etc..
