Car sharing is another way to drive green which is gaining in popularity, especially in urban areas. People who may not drive every day but still want a car to run errands (差事) or drive on weekends benefit most from car sharing. Car sharing is usually run by a service like Zipcar, though there are nonprofit (非营利的) and informal car sharing services. Members pay a monthly fee and have access to an entire fleet of cars when they need one. The cars are parked in fixed spots around the city, so members only need to make a reservation,
and then go to the pick up spot.
