It would be great if someone could think up a better treatment for aggressive tailgaters than to slow and pull over for them, but so far that's really the best way out. I did see one guy who had a dual windshield washer set up, one of which would spray (blinker?) fluid on the tailgaters windshield. I've tried turning on 4way warning flashers, which sometimes has an effect, but more often is ignored.
