Nobody tailgates me. I drive faster than them.
Seriously, I don't put myself into situations where I can't get out of someones way, wherever possible. I drive pretty fast but if someone want's to go faster than me, or is approaching me quickly from behind, it's either a cop, or someone that I am going to let by. I don't block. I hang in the right lane always, I'll go left to pass, and then back to right.
If a moron happens to be tailgating me on a road with no passing areas, like a country road, I will typically slow down and add more time between him and I. 30 feet at 60mph is much shorter, timewise, than 30feet at 30mph. If I have to stop short, I don't want this idiot (usually on the phone) in my backseat.
When I was younger, I used the handbrake technique on tailgaters. No brake lights and my car slows down. Now thinking back, that was certainly a wake up call for the tailgater, but a STUPID thing to do.
