I used (key word= "USED") to do silly things as a young lad......
Like i had a spark plug taped to the fairing up within easy reach of my left hand. Then if an idiot did anything stupid enough, I'd get in front of him and let the plug fly... does wonders to a windshield at speed. (I actually never did this, but had friends that did)
But uh, now-a-days, the worst is boot to door or kevlar knuckles to windows, but mainly horn and shaking head in disgust.... gotta try and be sensible and be a positive ambassador of the motorcyling community.....

so, anyone else have "ways" of dealing with dumbasses on the roads??? my wife thinks i'm nuts, but i think that you have to let people know what they have done wrong so that they don't do it again (or to a worse degree
