Well,PaMatt! I'm afraid if I tell it,some youngsters will get in trouble on account of me,or it will cause a wreck(really, I spoke before I thought in this instance). I don't want to be indirectly responsible for someone causing panic behind their moped so I better not say. Sorry I mentioned it. But I'm gonna try it out at slow speed on a country road, the next tailgater that molests me. I think at slow speed it is a good lesson for the tailgaters, and will make them back off. But they might get a little mad at me. At faster speeds it could cause a dangerous swerve. I really like the `smoke screen' idea the best.
