Car sharing has gotten a boost with GM announcing its OnStar subscribers can now rent out their cars using the RelayRides car sharing service. There are many car sharing services…ZipCar being one of the first and most widely known. But many of the original sharing services owned their vehicles and insured them on fleet policies. This new model of car sharing, where the vehicles are owned by individuals, creates insurance problems. Depending on what state you live in, you may or may not be able to find insurance for your car while it’s being shared.
