CarShare.HK is a car sharing platform that allows car owners to rent out their vehicles when not in use, generating additional income, while also giving renters affordable access to cars. It aims to capitalize on the large number of privately owned vehicles that sit idle for most of the day by building an online marketplace and community that connects car owners and renters. The presentation makes the case that car sharing represents the future of transportation in dense cities like Hong Kong by promoting affordable access and reducing the number of private vehicles on the road.
