Quite a lot, actually. Certainly relative to almost all other areas of the country the rate of car ownership is low, but the streets are so packed with parked cars that many vehicle owners are willing to pay for private storage with monthly rental rates that are typically between $450 and $600.<p>My impression, though, is that most car owners are not using their cars for intra-Manhattan travel, which is what Uber is doing a lot of. Rather they&#x27;re using their cars to travel to NJ, upstate NY, Long Island, or other areas where taking an Uber isn&#x27;t practical.
