Carsharing or car sharing (AU, NZ, CA, TH, & US) or car clubs (UK) is a model of car rental where people rent cars for short periods of time, often by the hour. It differs from traditional car rental in that the owners of the cars are often private individuals themselves, and the carsharing facilitator is generally distinct from the car owner. Carsharing is part of a larger trend of shared mobility.
Carsharing enables an occasional use of a vehicle or access to different brands of vehicles. The renting organization may be a commercial business. Users can also organize as a company, public agency, cooperative, or ad hoc grouping. The network of cars on the network becomes available to the users through a variety of means, ranging from the simplicity of using an app to unlock the car in real time, to meeting the owner of the car in order to exchange keys. As of January 2020 the world's top city for car sharing is Moscow with more than 30,000 vehicles (though in Moscow almost all carsharing cars are owned by large facilitators).
