What's the German word for "zing?" Probably "zing," now that we think about it.

As Americans, we often express our personalities with our cars. We also express our frustration with other people through their cars. We key them, we leave passive-agressive notes on the windshield, and we occasionally hit their cars with fists, golf clubs, or our cars. Although satisfying, all of these things are petty, destructive, and unoriginal. So everyone appreciates a unique take on car-based rage, from the barely-better-than-keying angry message scrawled in soap to high art brushed onto a dirty windshield. Here are some of the best ways we've ever seen aggression, boredom, or creativity expressed on the ultimate American canvas: the automobile.
