So...he uses his personal car to drive for Uber, then deducts the cost of the car from the money he made and says he ended up with nothing? It's like someone running AirBnB in their house and spending all money on mortgage and then saying that they make no money on AirBnb. Unless, of course, he uses the car for absolutely nothing else apart from driving for Uber, and wouldn't get a car otherwise.
With AirBnb, you rent out an item that is mainly fixed costs and incurs little variable costs per utilization. With p2p car rental like Get-around, it's the opposite. with Uber, it's even more so on variable costs, as it actively requires your time.
