Okay, but you can expect a car to last upwards of 10 and you own it. If you decide you want to drive down the coast, you can do just that. I think services like this are way overhyped and wouldn't exist if they saved you money.
uber makes money on every ride. they operate at a loss annually because they invest everything in expanding to avoid paying taxes - like most companies do.
It's also true that it's not sure they will ever reach profitability. Therefore, my comment.
