The one doing the tailgating is the one endangering lives. Tailgating is not just obnoxious, it kills people. What do you propose when someone is, effectively, purposely endangering your life?
My life is worth enough to me that I try to avoid people like that. Pulling over to let them pass is pretty darned effective, and the loss of a few minutes of my time is a small price to pay. In the case that I'm on a multilane road, in the rightmost lane, and they refuse to pass, I just put the cruise on. The amount of effort they have to go through to stay close usually encourages them to pass. And I don't have to go through any stress because I've put the car in control of the speed.
