Decentralized ride sharing

Me and a few friends are very into the crypto space and think that crypto is a very easily solution to making ride-sharing more affordable and profitable for drivers. We plan on creating a protocol that allows users to post up rides in a sort of auction system where both the driver and rider propose the price they want to pay to find a middle ground which will hopefully allow both parties to be satisfied with the price paid. Before we slave away designing this would people actually want to make the switch? If not what kind of safety nets/ features would you need to make the switch? Uber takes such a large percentage of fees we want to make this as a big fu to lyft and uber for taking such a large portion of the money paid for a trip.
