Following a collaborative consumption trend, existing car owners can rent their cars to other people for a short period of time. This use case allows Android mobile phone users to rent a vehicle temporarily on-demand at a variable fee depending on the distance travelled or usage.
Beta-testers can act as a driver or as a passenger. The driver is a person who wants to rent a car and drive it for a short period of time from one point to another. The passenger is a person who wants to share a car with other people (at least with a driver) for a short period of time from one point to another.
