You prefer Uber by ten times? What does that even mean? But on a serious note, could you share some of these 'well-documented' features and benefits? I agree that taking a taxi in many US metropolitan areas is no great joy, with vehicles smelling of dead rodents and drivers generally of the just arrived and clueless variety. In many other parts of the world a professional, trained and licensed taxi driver is preferable to some guy with a car and a Garmin nav system.
