This is not necessarily a win for everybody. I can foresee a situation where cabs start to favor only bookings/hailings from this app, since the fares (i.e. people getting into the cab) clearly have money (since they have a smartphone) and will hopefully tip better. The rest of us schmucks trying to hail a cab the old-fashioned way will be out of luck, since all the cabs will be waiting to pick up a smartphone fare.
