A big problem I've seen with the proliferation of these apps is that I've seen drivers with three or four devices, (which makes sense from the driver's perspective--maximizing opportunity), but even though I'm in the car paying a fare, they show up on the other apps as available! The result is that when you put out a call for a ride, even though it shows tons of vehicles available, most of them are actually currently occupied. As TFA points out, this leads to distrust since as a rider you can't actually be sure you'll be able to get a ride. I think the app makers need to encourage riders to report to them when they see drivers using other apps and misleadingly showing themselves as available. I know I'm going to start doing it.
