Clearly you have never driven in Europe. If you are in the inside lane slowly passing someone with your cruise on, and you see someone come up behind. Common road etiquette would be to step on the gas (you don't even need to disengage the cruise) and pull to the right as soon as you can. Instead you thought that your 20 over was ok, but his 25, 30, 35, whatever over was not, and you became self-righteous and decided to teach him a lesson. Well, I guess you learned the lesson! I agree that he over reacted by smashing your mirror. I would have just pulled in front of you and rolled off the throttle for a second or 2, then be on my way. You know, do unto others as they just did unto you, but not escalate the situation. Since you don't ride, you may not be aware that your actions have serious life threatening consequences to riders. He was just trying to encourage you to actually pass the truck, not just sit beside it. But instead, you did the opposite. So I guess there were 2 a...oles in that situation.
Btw, I can't believe that you actually joined a motorcycle forum just to rant about this, especially when you took the first aggressive move. I'll get my popcorn out!
