There are companies that get a contract rate with Uber to say, have X cars on the road 24/7. They in turn hire enough drivers to keep the cars moving all the time.

I'm fascinated by how logistics work, so I was asking my Uber driver a bunch of questions. He explained the above to me and said he was referred over to one of these companies because he didn't (or couldn't) buy his own car at the time.
