Cars are increasingly moving to a more-or-less rental model, with lots of finance and little eventual ownership. But this doesn't solve the "less garbage parked" problem; for that you need short-term rentals and although ZipCar and others are making inroads there are real challenges here: the demand is bursty (everyone wants a car on a sunny weekend) and the model is inconvenient (can't leave stuff in your car).
