This is a bit of a confession and not something I am proud of.
Don't really know why but I got into a huge row with a driver the beeped at me as he passed. It was on an urban dual carrigeway and I was about a metre out from the kerb in the left lane with queuing traffic about 200m ahead, which is where I caught him up again and starting filtering up the middle.
He then opened his window and starting remonstraing with me for riding too far out and holding him up. Next thing I know is the red mist descended

and I continued the argument with him for around a mile as the queue moved along and I stayed alongside at his window.
I have never done this before and I didn't make a rational arguement (can't really remember what I said), so I apologise to anyone else in Edinburgh that has trouble with a gold BMW as it is probably my fault
