Being a responsible kind of bloke I can't condone road rage, but having been a hairsbreadth away from casualty on a few occasions I can honestly say that sometimes my thoughts do turn to responses beyond a good shout and the single finger salute. Cycledog wants guns, I want a portable EMP device to disable car electronics..read the thread of comments on this post on an excellent bike blog.
CycleDog: "Everyone who uses the public way has both rights and responsibilities. That includes motorists, cyclists, pedestrians, and even horse back riders or horse-drawn vehicles. I'm getting fed up with motorists who think that their larger, heavier, more powerful vehicle gives them a greater right to use that public space, and I'm getting especially fed up with the pencil-necked geeks who use their vehicles as weapons. It's an annoying problem, and that problem has a solution.
Cyclists should carry guns."
