Merc drivers?
I have always joked that they are inconcedirate prats but today they proved it once again, this morning at a crossing, car in front is going straight ahead as well as me so I sit behind waiting next thing I know a Merc sqeezies itself next to this guy to go straight as well KNOWING I was going straight what a tit!!
So the question is are Merc drivers that bad really from my experince YES

In my experience they come a close second to Beemer drivers with Smart Car’s coming a close third

Coming to work yesterday I was in the left lane and had a Merc driver behind and to my right so close he was over the line and nudging my panniers to try and inch forward, pushing me off balance because I couldn’t go anywhere. Don’t think it was deliberate, just completely olivious in his cosy little German cocoon. Didn’t stop either till the Bandit rider behind me thumped his wing and yelled at him. Thanks mate, whoever you were.
I agree, BMW drivers generally tend to be more agressive and worse than the Mercs.
