As the saying goes: crazy enough to seem foolish, foolish enough to seem romantic.
Admittedly, the concept of this "the Hitch" is a pretty absurd thing, but it's particularly interesting. It's a belt with three large suction cups on it. What is it used for? For hitchhiking, but its method is quite stylish. All you need to do is take advantage of the traffic lights, walk over, and stick yourself on the car body. The designer, Robert Nightingale, ensures that you won't fall off.
