How many of those angry drivers are going to give notice to the cyclist that they intend to do harm rather than just running them over?
You can't prevent that. But let me give you a few scenarios. Motorist buzz cyclist all the time and then yell at such cyclist should the reach them at a stop sign or stop light. Cars cruise silently behind cyclist and honk the hron in potentially dangerous moments for the cyclist, causing them to be distracted when they should be focused on the road. Male motorist sexually harass female cyclist all the time and such women are vulnerable as they cannot answer back.
When I was riding in Florida, I've been hit by beer cans and other flying objects from cars. That is a felony on their part and dangerous. In one case, I reacted with a middle finger. This resulted in the big coal rolling truck stopping up 100 yards ahead and the guy yelling at me as I passed. Think about this for a minute. The guy hit me with a can, when I raised a finger, he stopped for a possible confrontation. This is somebody who wants you to fear for your life, and in most cases, cyclist do not carry. It just isn't practical. So they can do so with little risk of having resistance. But an awareness campaign by this Armed Cyclist Association with help from the NRA would make more people aware that some people do ride armed. In fact, to promote more people being armed, we would partner with a well known holster company for a holster that can be comfortably worn while riding in the aero or road bike position. We would also print up jerseys that say, I ride, I vote and I'm armed in highly visible print. I think I'm on to something.
"In the world I see you are stalking elk through the damp canyon forests around the ruins of Rockefeller Center. You'll wear leather clothes that will last you the rest of your life. You'll climb the wrist-thick kudzu vines that wrap the Sears Towers. And when you look down, you'll see tiny figures pounding corn, laying stripes of venison on the empty car pool lane of some abandoned superhighway." T Durden
