Very simple; Break hard and push accerator down to the floor (only if you have enough space infront). Always seems to work for me :) Also if they hit me, their problem so nothing to worry about :). If there is not enough space infront of me then I just go even slower, letting them smash the horn and flash lights at me. Once that is done and they still dont push back then it calls for emergency treatment. What I then do is spray my screen washer and it sprays the person behind me, i dont stop until Ive probally emptied half the tank full of water he he, they normally push back or get distracted. I love tailgaters!
