Sometimes what they charge you is not "market price" though. On my last trip my Uber driver took me via a huge curve and the charge ended up being ~ 40 dollars more than the projected value. I've filled out a form explaining the situation and most of the 40 dollars were immediately deducted from the fare on submission. I don't know whether the driver made a mistake or took me on a "trip" deliberately, but if I was in a normal taxi, I would either have to pay, or fight with the driver. Not defending the company culture, but the app does protect the consumer from some level of undesirable taxi driver behaviour.
