Car sharing is a model of car rental in which people rent cars for short periods of time, often by the hour. The car has to be located close to the customer's residence or workplace, so cars are distributed in the community. The rental process has to be self-service and cars need to be available 24 hours a day. The primary markets are large metropolitan areas, universities, and corporate campuses where there is a relatively high burden of car ownership. The car-share operator pays for maintenance, parking, gas, and insurance of the vehicle.
