One way to view Uber is as a redundant array of inexpensive drivers. Since the individual contractors are fully fungible and numerous, one will usually be available to take on any new request. It is an anomaly of the Uber model that the barriers are incredibly low, the service is provided very quickly and that a significant number of drivers are willing to idle waiting for a ride. This is reflected in the relative low pay. Even then, I bet Uber has retention or reliability problems with drivers.
