'Less shit than the average human at it' is a really low bar to set for modern computers, even if Tesla fails at that poor standard and Cruise is currently top of the game. We still need much higher bars when we're talking about entirely automated systems which are controlling speedy large chunks of metal, or even other smaller-scale-impact-and-damage systems. Systems which can't just hop out, ask if the victims are OK, render appropriate first aid, accurately inform emergency services, etc.
The more automation, the higher the standards should be, which means we need to set legal requirements that at least try to scale with he development of technology.
