an idea: 1 way of getting rid of tailgators is to keep a brick in your car, and when they get up your ass hang your arm out the window, while holding the brick. make sure they can see it, then swing your arm in a backwards motion so ti looks like your lining up the brick to hit their car.
I think it should scare a few people off.......or you could just throw it, depends how crazy you are........
