I'm not saying this is true in all instances, but did you ever think maybe you are doing something wrong to get tailgated? Maybe the people behind you are just as frustrated as you are with them. Do you take 5 mins to accelerate to the speed limit from a stop? Do you cruise in the left hand lane on the freeway going the speed limit or less with a line of cars behind you? Do you drive 5-10 under the posted speed limit? Just a few examples. I can say I'm a tailgater at times because some people just don't get it. I would suggest not slamming on your brakes and maybe self reflecting a bit.
