A quick check that nothing was coming and I slowly crept to near the front. Second place to be exact.
When the lights changed I just pulled off and was about to blend in behind the front car when No 2 car blasted


As I am not a violent or confrontational type of chap I just let it go and waved back at him thanking him for letting me in!
At the next lights on Bon Accord at Fonthill Road he was still in 2nd place behind said 1st car and they were both turning left - I was heading straight on - so he never gained anything anyway,.
So was I totally in the wrong or did I just meet a dickhead?
thanks in anticipation
