In Tesla’s defence; their system works anywhere even when the road is not mapped, but these robo taxi services only do on selected geo-fenced areas. Atleast that’s my understanding of it. It’s conceiviable that what Tesla is doing by completely relying on neural nets is the right way to go where as the other with human programmes is a dead end. Only time will tell I guess. I’m not educated enough on Cruise and Waymo in general so I can’t really comment on that.
