That doesn't address any of the safety issues from the post you replied to. Convenience will not save your life in an accident, should an accident happen. Convenience doesn't prove the driver is who he says he is. Regulation in the taxi trade was probably built up over many years to tackle the issues that arose over time, Uber will eventually fall foul of the same or similar regulation, eventually pushing prices up. What Uber are probably doing is refroming the taxi trade and eventually the two services, Uber and traditional cabs, will find a middle ground and merge into one service.

Is there a reason why a black cab driver in London, Manchester or Edinburgh couldn't register as an Uber driver and play for both teams?
