Could this be simply solved by having their star rating influenced by % ride drops? Uber can provide its price estimate as just that - a kelly blue book value so that riders can compare and contrast? Most customers will search for a range of rating + price - so the market can regulate itself. I mean we accept amazon displaying user ratings - so I don't know why this won't work.
