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 car sharing facilitator is generally distinct from the car owner. Car sharing is part of a larger trend of
shared mobility.
Car sharing 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

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. The majority of car sharing vehicles in Moscow are owned by private companies.

in 1948. By the 1960s, as innovators, industrialists, cities, and public authorities studied the possibility of high-technology transportation – mainly computer-based small vehicle systems (almost all of them on separate guideways) – it was possible to spot some early precursors to present-day service ideas and control technologies.
The early 1970s saw the first whole-system car share projects. The ProcoTip system in France lasted about two years. A much more ambitious project called the
Witkar was launched in Amsterdam by the founders of the 1965
white bicycles project. A sophisticated project based on small electric vehicles, electronic controls for reservations and return, and plans for a large number of stations covering the entire city. The project was abandoned in the mid-1980s.
In July 1977, the first official British experiment in car sharing started in Suffolk. An office in Ipswich provided a ''Share-a-Car'' service for "putting motorists who are interested in sharing car journeys in touch with each other." In 1978, the

Carsharing in North America began in Quebec City in 1994 after Benoît Robert started a company called Communauto that is still a leader in car sharing globally. Cycling advocate and environmentalist Claire Morissette (1950–2007) played a major role in its evolution starting in 1995, when Communauto established itself in Montreal as a private company.
Rapid growth in the United States

The first car-sharing company in the U.S. was CarSharing Portland, founded by Dave Brook in March by 1998 after a visit from Conrad Wagner of Mobility Switzerland. Conrad and Dave would also help establish
Flexcar in Seattle, which launched in 2000, the same year as competitor Zipcar on the east coast. In April 2001, Carsharing Portland, then with 25 vehicles, merged with Flexcar, as its first expansion city.

Zipcar accounted for 80 percent of the U.S. car sharing market in 2010
and half of all car-sharers worldwide with 730,000 members sharing 11,000 vehicles.
In 2008, City CarShare introduced the first wheelchair carrying car share vehicle, the ''Access Mobile'', specifically designed as a fleet vehicle shared with non-wheelchair users.
Car sharing is noted as a tool for achieving vehicle miles traveled and greenhouse gas emissions reduction targets in the California Transport Plan (CTP) 2040 to reduce congestion and pollution.
Development and growth
Car sharing has also spread to other global markets with dense urban populations (such as Argentina, Brazil, China, India, Mexico, Russia and Turkey) given that population density is often a critical determinant of success for car sharing. Successful car sharing development has tended to be associated mainly with densely populated areas, such as city centers and more recently university and other campuses. There are some programs (mostly in Europe) for providing services in lower density and rural areas. Low-density areas are considered more difficult to serve with car sharing because of the lack of alternative modes of transportation and the potentially larger distance that users must travel to reach the cars.
Many building developers are now incorporating share-cars into their developments as an added value to tenants, and municipal government bodies around the world are starting to stipulate the implementation of a car sharing service in new buildings, as a sustainability initiative. These trends have created a demand for a new model of car sharing – residential, private-access share-cars that are typically underwritten by the

According to
Navigant Consulting, global carsharing services revenue is expected to grow to billion by 2020, with over 12 million members worldwide. The main factors driving the growth of carsharing are the rising levels of congestion faced by city dwellers; shifting generational mindsets about car ownership; the increasing costs of personal vehicle ownership; and a convergence of business models. Carsharing operators increasingly opt to brand parts of their fleets with third-party advertising in order to increase revenue and improve competitiveness (
Transit media).

Types of car sharing
Generally, car sharing programs fall into one of four sharing models: round-trip, one-way, peer-to-peer, or fractional.
Station-based car sharing
With station-based (or round-trip) car sharing, the cars are permanently stationed at designated stations, typically simply reserved parking spaces. Members pick up the vehicle at the station, and must return it there. The car must usually be reserved for a specific amount of time in advance, and must be returned before that time ends. Payment is usually both by the hour, and by the distance driven. In exchange, a vehicle can be reserved days or weeks in advance, and it is often possible to reserve a specific type of vehicle, such as one with more seats or greater cargo capacity.
One-way/free-floating car sharing
One-way car sharing enables users to begin and end their trip at different locations through free floating zones or station-based models with designated parking locations.
As of 2017, free-floating car sharing is available in 55 cities and 20 countries worldwide, with 40,000 vehicles and serving 5.6 million users, with

representing the majority of the market. In Europe, free floating services took up more than 65 percent in car sharing membership.
The service is expected to reach 14.3 million users with more than 100,000 vehicles by the end of 2022.
By conventional companies
In
corporate car sharing, the company shares the vehicles and allows multiple employees (rather than just one) to make use of a company car, at times when they actually need it. The vehicles are made available from a
corporate car sharing pool, and shared for a fixed or flexible period of time. One shared car could replace up to 8 non-shared cars. However, car-sharing does involves an additional processing and associated costs. Still, it reduces fleet-related costs over the long term and allow employees to save not only on costs but also on time.
Peer-to-peer car sharing
Peer-to-peer car sharing, sometimes referred to as P2P or Personal Vehicle Sharing,
operates similarly to round-trip car sharing in trip and payment type. However, the vehicles themselves are typically privately owned or leased with the sharing system operated by a third-party.
Fractional ownership
Fractional ownership allows users to co-own a vehicle and share its costs and use.
Neighborhood fractional ownership car sharing is often promoted as an alternative to owning a car where

can be used most of the time and a car is only necessary for out-of-town trips, moving large items, or special occasions. It can also be an alternative to owning multiple cars for households with more than one driver.
Difference from traditional car rentals
Car sharing differs from traditional car rentals in the following ways:
* Car sharing is not limited by office hours.
* Reservation, pickup, and return is all self-service.
* Vehicles can be rented by the minute, by the hour, as well as by the day.
* Users are members and have been pre-approved to drive (background driving checks have been performed and a payment mechanism has been established).
* Vehicle locations are distributed throughout the service area, and often located for access by

.
* Insurance: (this section is US specific) state minimum liability insurance (only $5000 in some states), comprehensive and collision insurance. They do not provide uninsured, under-insured or personal injury protection insurance.
* Fuel costs are included in the rates.
* Vehicles are not serviced (cleaning, fueling) after each use, although certain programs (such as

or
GoGet) continuously clean and fuel their fleet. Members are usually required to refuel the vehicles if fuel runs low, with the cost borne by the car sharing provider.
With car sharing, individuals have access to private cars without having costs and responsibilities associated with car ownership (except for fractional ownerships).
Some car share operations (CSOs) cooperate with local car rental firms, in particular in situations wherein classic rental may be the cheaper option.
The insurance policies on carsharing greatly varies among companies, but all car sharing firms provide insurance that at least meets the legal minimum requirements for the given region of operation. Rob Lieber of ''The New York Times'' has criticized car sharing firms such as Zipcar for the paltry coverage afforded car sharing drivers.
Technology
The technology of CSOs varies enormously, from simple manual systems using key boxes and log books to increasingly complex computer-based systems (e.g. partially automated and fully automated systems) with supporting
software packages that handle a growing array of back office functions. The simplest CSOs have only one or two pick-up points, but more advanced systems allow cars to be picked up and dropped off at any available public parking space within a designated operating area.
Once the reservations are completed and confirmed, the car will then be delivered at the time and place scheduled. There will be a small card reader mounted on the windshield. Once the customer places their membership card on the reader, it will use what is called
blink technology to activate the time and unlock the car. The reader will not work until it is time for that specific reservation. The keys can then be found somewhere inside the car such as the glove compartment. Depending on the company, the customer may be provided with a key to a lock box that contains the ignition key itself.
In some cases the car can be unlocked using a mobile phone and the car can even be started using the phone as well.
Many car sharing networks price their services as a small start up fee and then a mileage fee for the distance driven in the car. Usually the app will include insurance, gas cards, and upkeep to their fleet of cars at no additional charge to the customer.
