Similarly, I will deliberately slow down in a clear passing zone to make it easy for the tailgater to pass - a couple of times, anyway; if they don't take the opportunity, then it's their problem (except that they're still on my tail).

Btw, contrary to popular belief, tailgaters are actually of the crocodile family, and no relation to alligators whatsoever (notice the difference in spelling). Occasionally, tailgaters are confused with gator-tails, with embarrassing and even disastrous consequences.
