Taxi is way to expensive yes also not needed since i have no problem affording a car. I drive a prius hybrid due to keeping the environment in mind and the next car i hope will electric. I doubt my next car will be selfdriving but i hope the one after the next one will be.

When selfdriving becomes normal many people might have the car work as a taxi when its not needed by the owner. This might reduce the price of transport alot, making it easy and cheap enough for people to be able to drop car ownership if they dont want to. (you would just order a ride through an app and it will collect the nearest selfdriving car that is awailable)
