All of the Uber style businesses are also based around convenience, and as a consumer my elasticity for convenience is not very elastic(I don't know if this is the same for the general population). Pre-Uber, I can almost count on one hand the number of times I took a taxi somewhere but Uber made it cheap and fairly frictionless, so why not! Now it is still fairly frictionless but more expensive, and is just not worth it as much.
