Yeah, same as most of the others here, I've punched mirrors, kicked doors, thumped hoods, "dropped" pocket change on tailgaters, run up on people's windows, etc. It is quite gratifying to see a traumatized yuppie sitting behind me in his Beemer, 7 carlengths back at the stoplight because he's afraid to get near me again after he tried to bully me out of a lane. About half of them are just the same idiots we always see, but I've been seeing a lot more cagers doing blatantly rude/ dangerous things, like trying to merge on top of bikes or "fake" swerving to see if they can scare them. Of course, we should remember that we're kind of relying on shock/surprise and pure intimidation when we take aggressive actions with moving cars-- we are rather vulnerable if they decide to push back. Also, these: http://www.selfdefenseproducts.com/Fingerless-Lead-Lined-Defense-Gloves-p-17074.html Oh, and that F-250 that backed you up is probably just another rider. I've done that too, when I'm stuck driving my truck-- see a car bullying a bike, bully the shit outta the car. For great justice.
