Dumb question, do the cybercab thingies not drive themselves? Having a safety driver doesn’t disqualify them if for the vast majority of the time they’re autonomous. It just means they’re earlier into chasing 9’s than Waymo.

The characterisation of “level 5” autonomy as the car handling any conceivable circumstance (not that you explicitly made this claim here) is just silly. Humans can’t handle any conceivable circumstance either.
