Yes but the initial outlay is the drivers and not Ubers. Also they don't pay for the car they just pay a bit toward it, if you buy the car you have maintenance and insurance to pay for directly. If they had to buy a fleet of vehicles for their entire operation in pretty sure their losses would be an order of magnitude above 3bn.
