"No reason this shouldn’t work - there are really three distincy car-sharing spaces: Taxi competitors (Sidecar, Lyft, Uber); Rental competitors (CityCarShare, ZipCar); and personal rentals (GetAround, Relay Rides) and all have their purposes.   I’ve used most of them, and last time I checked, ZipCar’s rates were significantly higher than GetAround, as they had to be since they had to cover the average cost of car-ownership, rather than cover the marginal cost of car-using.  for the person with a car sitting idle while they are at work or the 2-car owning family that rarely needs both GetAround offers a great solution to help cover the costs, and the experience worked well for me each time I used it."
