The trillionaire can't spare $1m. That seems like quite a small ask for a wrongful death.

after the inevitable loss of life due to a spaceflight event (everything breaks eventually), he's likely to deny that spacex had anything to do with it.

I think the human "driver" of that car will be charged with at least recklessness. Even if you are in a botcar you still have ultimate responsibility for safe operation. From the vids I've seen and the damage to a brick wall it had to be going at least +60 MPH in a residential neighboorhood. If he was paying attention he would have disconnected auto mode and hit the brakes long before it crashed. He was probably on his phone at the time or asleep.
