Matewis: You have to have a thick skin, but it would be tough in your case because it seems that you ran into some petty morons. It happens :P Something similar happened to me (some guy ina 3-series bmw), except the guy drove by and gave me the finger :D only I have no idea what I did to piss him of. I think I might have overtaken him at a tollgate and then seriously pissed him of by sticking to the highway speed limit.
We've got this wonderful thing over here called minibus taxis. I don't want to post links, but try and google it. You'll find videos of them skipping red lights, crashing, (which they do routinely just before or just as it turns green for the other direction), assaulting pedestrians, forcing their way into the front of long ques of cars and otherwise acting like complete asses. Mostly they are sort of ok, but when there is a lot of congestion, or they see that a traffic light is going to turn red on them, then it's as if they go completely mental. And unless your driving a bulletproof car, you don't want to be anywhere near a taxi that is driving outside of its territory...
