While there are other companies like ZipCar or Car2Go have already the technology, the experience, and the infrastructure on how to own cars, how to service cars, and how to bring the users and those cars together. On the other side, Uber does not own any car neither have any infrastructure for those cars. So it should be easier for ZipCar, Car2Go and alike to exchange those cars with self-driving cars vs. Uber to build up that infrastructure.
