@ErickaSimone I want all cars to be taxis, just as a basic privacy and safety thing, but since I'm not rich enough to afford a personal chauffeur, a car is the second best option. Mixing with other humans have put me at risk and actual receipt of assault more than once. Buses and trains are the worst possible option for me. It isn't infrastructure we'd need to change, it is the basis of human behaviour itself that would need to be changed first. That is less realistic than self driving cars.
