Car-sharing is a service that allows individuals to rent cars for short periods, often by the hour or day. This system provides an alternative to owning a vehicle, making it convenient for people who need a car occasionally without the costs of maintenance, insurance, and parking. Users typically reserve a car through a mobile app or website, pick it up from a designated location, and return it after use. Many car-sharing programs operate in urban areas, where public transportation may be more accessible. Companies like Zipcar and Turo offer various vehicle options, catering to different needs, from compact cars to larger vehicles for group travel.
