The 5th Wheel: An Ingenious Parallel Parking Hack
A clever driver from Cairo, Egypt has revolutionized parallel parking with a fifth wheel built into his car. The extra wheel in the rear is perpendicular to the others and under the trunk (which looks like it's actually stored in the trunk compartment), and can be raised and lowered for easy parking in tight spots. You can even ditch that old, rusty tire jack and swap out a rear flat tire in record time.
Well, maybe the driver didn't revolutionize parallel parking, since someone back in the '50s already invented it in California. Still cool, though.
