I keep getting the urge to ram other inconsiderate drivers off the road. It is worrying, as I could do it one day. I get the same old inconsiderate drivers every day. I am on a roundabout, where there are 3 lanes, 2 to go straight on, 1 to go right. The two lanes are always busy, the outside lane fairly empty, and every day a small number of drivers go up the outside lane, and then try and force there way back in once the lights go green. The road markings are clearer than a clear road, on a clear day in clear land. How do I deal with them, without my blood pressure raising?
