Actually, this might happen in the future. You could totally see it as, any independent person who want to offer rides as a service might need a platform for it. And if Uber offers itself more as a marketplace, this could make sense. Pay Uber a fixed price to be on the app, or have them take a percentage, and be routed through calls, but set your own prices for the rides. I'm surprised there isn't an Uber like app that operates this way yet actually.
