What a 24 karat c*nt. So I'm driving along the A413 Amersham Road today around midday, when I see a dark coloured fellow E55 behind me a way back. You start to get pretty close to me, which I thought was cool, you recognised another E55 and seemed a little playful. So I drop a gear and gap you about 10 car lengths. But there's now traffic ahead as we approach the double roundabout near Chalfont St Giles. You then get close to me again. VERY close, way too close. I still give a thumbs up, as I still have respect for a fellow AMG driver. Not seen too many around here lately. Not sure if you thought I was flipping you off, because you obviously got triggered and got within inches of my bumper. At this point I'm slowing as several cars are in front of me as we reach the double roundabout in the now 30mph zone. So you thought it would be good to try to overtake me in this single lane road, into oncoming traffic, with absolutely no gap/space ahead of you. Moron. Immediately recognising your stupidity, I hit my brakes hard and pull to the left, leaving you JUST ENOUGH space to get ahead of me. I just saved your life because there was oncoming traffic on the other side you almost hit. You are welcome. Oh but if only the story ended here... So now traffic is rolling about 10 mph as the double roundabout is right ahead of us, with 3 cars in front of both of us on this single lane road. You now for some reason attempted to overtake all of those cars and blast through the roundabout. This did not go so well for you, or the little car you side-swiped travelling in the opposite direction. His sideview mirror exploded and rained plastic and glass onto all of our cars. The little car obviously pulled over whilst you sped around everyone and drove off. You have now overtaken 4-5 cars, and it is impossible for me to try to safely catch up with you to write down your number plate. So well done. I did see you double back after about 5 minutes of driving, and I turned around to follow after you maybe getting your number plate this time. By the time we reached the original scene of the collision, that victim's car had already given up hope you'd return as it had been over 10 minutes by this point. So well done, you've now committed a hit and run. Was depressing seeing your mirror dangling down the side of your door. Your poor AMG didn't deserve that either. Another victim. I hope someone wrote down your plate number, there were certainly enough witnesses.
