If you're looking to save a little bit of money next time you travel, FlightCar may be the thing for you.  Instead of paying full price for a rental car, you can save up to 50% with this new method.

In exchange for not having to pay for parking at the airport when you travel, you rent your car out to other people while you're away.  FlightCar checks their driving record to make sure they aren't high risk, and they even clean your car before and after the rental!  Obviously, the car is insured when the renter is driving it.  So you arrive home from your trip, you don't have to pay a ridiculous amount of money for parking and your car is clean.  Win win, right?
