But, no one uses it, because uber and lyft have become kleenex or coca cola: the brand name associated with the basic phenomenon, such that consumers cannot even think about the phenomenon without thinking first of the brand and probably resorting to the brand.

If they wannted to innovate, every taxi stand would have a QR code to download their app, you set your destination while you're waiting in the line (if there is one), you get in the cab, the driver scans the QR code from your phone, payment happens via CC in the app, no surprises either. The phone app would show you the route, and then give an estimated price, and if there's an overage due to traffic/other problem, give me a notification on my phone. It would also let me set preferences for conversation/temperature.
