The vehicles owned by carsharing companies are often permanently parked in several locations throughout a city or a larger town. These locations tend to be near public transportation nodes (train stations, tram stops, bus terminals, etc.), which makes them easily accessible to carsharing members. In most cases, pre-booked carsharing vehicles are used to travel from such public transportation nodes to more remote destinations. In contrast to conventional cars rentals, carsharing also offers short-term option (hourly rates).
As the carsharing model only works in conjunction with a well-developed public transportation infrastructure, it is commonly understood within the "combined mobility" paradigm. Carsharing cannot (and doesn't intend to) replace public mobility options -- in fact, public transportation is a required component of the carsharing model. This means that carsharing is rarely a good option for commuters who depend on a car for their entire commute. For them, car pooling or ride sharing are better alternatives. Carsharing remains the ideal solution for those with sporadic travel or transportation needs.
