I've been thinking about the best way to defend myself after an encounter a few weeks ago in which a motorist in line behind me at a red light threatened to run me off the road or get out of his car to "beat my ass." I figured he was bluffing so I did my best to avoid responding to him (one of my new year's resolutions was to avoid escalating negative encounters while on the bike) and went my way when the light changed. Luckily he was bluffing and and ended up peeling out around me when the light changed (4 lane road). I didn't worry about it too much at the time but I've been thinking about it more lately and I'd like to have a better plan in the event that I do have to defend myself.
Background- I am 5'8", 130 lbs and wearing road shoes with spd-sl cleats 90% that I am on the road so getting into a fight would likely be disastrous for me. Obviously my first course of action would be to get the hell away but the entire purpose of this thread is to know what to do when I can't.
Right now my plan is to grab my frame pump or u-lock and strike as soon as the other person makes a move. If I had my u-lock I would target hands and arms because I figure that most people would stop after shattering a hand. I don't think that I would swing for someone's head because I don't know how I would stand legally if I actually connected, not to mention most people protect their heads first. Beyond that I have no idea what to do so if anyone has any advice regarding how to defend oneself while on rides then I'd like to know what to do.
P.S. I won't carry a gun
edit: My search is working now and I found some useful stuff so I don't know if this is necessary anymore...
