I still disagree, I think their explosion is the result of other factors. Medium-sized cities still had taxi cab services but they were more expensive and less used. Uber and Lyft had massive capital backing to essentially invade these cities with lower cost rides. Once that honey-moon is over (it's over in NY for sure) customers will be in the exact same place. Another factor is that there is more leisure money moving around in the middle class as opposed to before. To attribute Uber/Lyft to the cause of the culture change is just way off base.
