It's not always obvious, but many car leases don't allow you to drive with ridesharing services or rent your car to others. And it's no surprise as to why -- the high mileage and varying driving habits aren't going to help the car's condition when the lease is over. BMW, however, is sticking its neck out. It's trotting out a Car & Ride Sharing Lease for BMW- and Mini-branded cars that, as the name suggests, permits either driving for a service like Uber or renting your car to others. If the payments on your 3 Series are a little too difficult to bear, you can make some money on the side.
