I tend to agree that Uber and Lyft are qualitatively different from traditional cab companies although, as many others have said, I'm not sure they have much of a moat or economies of scale. For the overwhelming majority of Uber users, it's irrelevant that they're in 72 countries or even multiple countries. In fact, I'm sure many users would switch to a better service that just operated in their own city.
