What I would do if I could afford it is to buy a Hummer H1 and purposely wreck it. I want dents and scratches all over the front, sides of the body, and back of it. Then all I need is a bumper sticker that says "GET OUT OF MY WAY", a long rack of spotlights on the roof, and a sticker at the top of my windshield wrote backwards " ---> GET OVER".
Yeah flash my lights at a slow poke and see what happens. I hope they crap their pants.
