Going forward - I think it's important to not just categorically say all self driving cars are safer than human drivers. It's probably better to say I feel safer around Waymo and <insert other trusted company> self driving cars.
With such complexity and unknowns within the codebase - there is likely going to be a much higher amount of variability w.r.t. safety and AI decision making. I'm not so sure I'd categorically say a self driving car from say Nikola or some SPAC'd startup would make me feel all that safe.
