Uber isn't a ride-sharing service - it's a ride-hailing service. The only thing that makes people want to use Uber over a Yellow Cab is that with Uber I open an app, click "Request Uber," the app shows me where the cab is, gives an accurate time of their arrival, and gives me information about my driver. You want to compete with Uber? Those are fairly straight-forward features to add to existing cab-hailing apps. Uber's technological advantage can thus be nullified easily, leaving it only to compete on price. Plus, taxis have an advantage because of the heavier regulation around taxis making them (theoretically) safer. The sooner the world's cabs companies beef up their technology infrastructure the sooner this upheaval will stop. There will be no further privatization of public transport assuming the taxi companies realize this soon. Oh, and cab medallions are already privately owned.
