this is so rampant but they know they have a captive market (in many places, only uber or lyft are an option) so they abuse their position

I've had good experiences with Uber. I know others don't, but I have. I used to use Lyft but they treated me like shit so now I don't. If Uber starts treating me like shit I'm going back to taxis. If taxis treat me like shit I'll take the bus, walk, buy a car, or any of the dozens of other ways to get around, even if impractical. The market is only captive because people are lazy and weak willed.
