Don't these ride sharing services in urban centers just cause more people to travel by car? It seems obvious that this would increase congestion. The only thing it seems likely to reduce is the amount of parking spaces and idle vehicles in storage, less vehicle ownership. But now everyone, even those without cars or even driver's licenses, are just a smartphone app away from having a car shuttle them around for even the most trivial of distances. When you make something more convenient and accessible, it gets utilized more. A funny thing about the prospect of self-driving cars: what about the people who used to be in the driver's seats? I suppose some percentage of those will instead be passengers in the future - oops, even more cars on the road!
