Man - don't you just wish you could be behind the gun on this puppy when the next asshole cuts you off without a by-your-leave? I knew a man who was so incensed by rude drivers; he mounted a tiny laser on the front of his car. He used to love leaving little designs in bad drivers paint, until nabbed by a very observant cop on an extremely foggy night.
