Yep, I have to agree with the "blow them a kiss" crowd. Works everytime, most of them don't know what to do so they just keep on driving. I don't think I would ever stop and confront one of these nutcases, you never know what they might do. Oh, I've tried the peace sign, only rotated to the left my 90 degrees (I've seen some H2 owners use at an H2 ownership sign) - that really perplexes the hippy crowd.
