My concern with this is the problem of ensuring the safety of the person driving the cab and the real identity of the rider.
Lots of drivers will be reluctant because they can be stiffed on the bill. Lots of passengers will be reluctant to use it due to the inherent risk of riding with what is essentially a stranger.
