Why do you assume the surveillance will go away as they become cheaper? The taxi company know who is in their car and they have access to interior cameras if something happens. In many respects, it is going to be even more difficult to take a dump in one and get away with it than if a human was driving it. They have your credit card number and visual evidence of what you did, they will just charge your card automatically for things like puking.
