You're getting downvoted because this is both a bad business idea, and a bad product idea.

Uber and Lyft have proven that drivers and riders don't want to think particularly hard. They want a magic button that either a) makes a car show up or b) feeds them customers.

As for the business side, there's no good reason to think that this would even cut costs on Uber's side -- they still need to maintain all of their lobbying costs, their server and engineer costs to maintain the bidding app, their marketing costs, etc.
