Car-sharing means that a number of persons share the use of one or more cars. Use of a car is booked beforehand, the user paying a fee based on the distance driven and the length of time the car was made use of. Although this is similar in some ways to traditional car rental, it differs in the possibility it provides of booking a car for short periods of time and in the rental agreement being made for an extended period of time, rather than each time a car is used. In addition, each household has its own set.
