Do you class yourself as an aggressive driver?
I've had a few people tell me I am but I like to think of myself as enthusiastic.
I think most people get pissed at slow and hesitant drivers, as well as those who fail to indicate and have poor lane discipline, but do you get wound up and vocal?
I shout and swear and even gesture at times but to date I've only had one 'incident', however when he got out of his car he was a damn sight bigger than me so I managed to lose him.
