Whenever they get too close, tap your brake pedal lightly enough for your brake lights to go on, but not enough to actually apply the brake and slow down.
I just downshift a gear or two and let off the gas gradually … accelerate a bit … let off. The varying distance without brake lights generally creeps most tailgaters out, and causes them to finish their proctological exam.[/quote]
That would work for most user. What would work better is to just move to a slower lane. When people do that to me, I just gun it, pass that person and get into their lane, then slow down below the speed limit just the piss them off. If they try to pass me, I’ll just speed up to prevent them from doing so. If I’m really pissed off, I can pass them, and do a hard break check on them.
