> phone calls This can make things awfully complicated when you and the dispatcher don't speak the same language. > waiting around for a taxi to arrive The worst part about waiting for a taxi is the dice roll of whether one will actually arrive. Often in the case of a popular spot (like after the end of an event) the taxi could pick up someone else from the same location - or worse yet, not show up at all. The introduction of feedback associated with a specific driver has completely changed the incentive to actually show up and pick up the correct person.
