I’ve taken hundreds of ubers and it’s always been within cents of the price I was quoted. I’ve taken hundreds of cab rides and only a handful of times was in given a price before hand.

I think it’s fair to say I know the price when it comes to an Uber and even if they can drive around to raise the price, it’s going to be obvious.

And on that note, at an airport near me there is a close by convenience store and if the Uber doesn’t want to take the fair, it’s know they will sit in there and wait for the customer to cancel it so they don’t get the hit. I’ve had it happen to me, contacted uber, and they gave me a discount on my next ride. I’m sure they don’t want to give away money, so I assume they are dealing with the driver at that point.
