Cars are non of that and we have billions of them on the street.
Cars also became a lot more expensive due to their complexity which def creates problems for a lot of people who can't afford all of that. I'm really torn by this because I think its very good that my side mirror shows me if there is a car next to me but in our capitalistic economy, we are excluding a lot of people from affordable cars. Drive by wire needs to be cheaper and easier to fix/repair.
Btw. Waymos are slowly learning to drive on highways so I might agree that they drive saver than humans in certain controlled envs. For sure not in any environment.
