Re taxis, right now you have to pay for the human driver's wages, and for the driver's medallion. This makes taxis much more expensive. Re car seats, obviously if there's a lot of demand for them, driverless car companies will pre-install them on some of their fleet. This is a bit of a tangent, but also, Selfishness Does Not Work Like That. When you look at a totally "selfish" part of the economy (eg. consumer electronics, or sports cars), it often works beautifully efficiently - every year, we get better stuff for less money. When you look at "selfless" parts (eg. education, health care), they are often giant clusterfucks. Are there exceptions? Certainly. But one can hardly say it's axiomatic that "selfishness" = "bad". (Re healthcare, yes, in America it's unusually bad, but in Germany/Canada/Switzerland/etc. the price we pay per suffering alleviated still keeps going up and up and up.)
