I once saw a decal for the top of the windshield that read backwards "SLOWER TRAFFIC KEEP RIGHT". It reads the right way in the rear view mirror of the car in front of you. Now that I have an M5, I'm looking to see if anyone knows of a source for these. Thanks.
I want one of those horizontally scrolling LED displays - one facing forward for "get the f#%k out of my way" and one facing back for "get the hell off my ***" and "dim your f#$king brights." (Not to mention "you look pretty good from the shoulders up. How's the rest doing?")
A buddy of mine had a "Warning Sticker" stuck on the dash of his car near the passenger seat... it read something like:
WARNING: This is a competition vehicle equipped with a high-output engine! Safety harnesses must be warn at all times! Due to high acceleration and excessive cornering forces, female passengers are encouraged to sit as close to the driver as possible.
