Three days ago.. I was on my motorcycle, lining up behind a car just before a round-a-bout. It was around 5.30pm, so the traffic was so bad that only one or two cars could go a a time. When I reached the round-a-bout, a car hit me from behind and pushed me into the round-a-bout.. Luckily, there was no cars passing my section of the round-a-bout, so I just rode on and when I finally reached a road where I could stop by the side, the car that hit me stopped behind me.. The owner comes out from the car, and the first thing he said to me was, "You shouldn't have suddenly stopped in front of me!"..   
Okay, let me first point out that I didn't just suddenly just stop. I just slowly move towards the round-a-bout. The SOB said it like I was speeding and pulled of an emergency sliding break. 
Second, judging from his attire, he looked like a office businessman or something, so he probably was on the phone when he knocked me. Plus he was wearing a hand-free wireless earpiece thing.. 
And third, My brake lights and license plate got busted. The guy just broke his left signal light. And bitches to me like he was the only one who suffered..   
So I walked over to his car, grabbing a piece of broken steel or iron(I didn't really care anymore, as long as it was hard) on the ground on the way. And smashed his other signal light.. The guy screams "why did you do that?". I walked slowly got on my bike, still holding the piece of steel, and said to him while pointing the steel? at him: 
"Cuz you stopped behind me, dumbass". And rode away..   
True Story..This happened to me.
