Onstar

General Motors says its On-Star customers can now use their GM cars to make some extra money - by renting out their vehicles.

Car-sharing allows someone to rent their personal vehicle to people who don't own one. Typically the borrower just needs a car for a few hours, for errands, grocery store visits or the like.

Now, GM car owners who subscribe to Onstar can rent out their cars through a car-sharing company called RelayRides.
