I was riding through the middle of the city a few minutes ago on my way to the office when the driver of a courier van suddenly decided he wanted to be in the same place as me. My first thought was "This is bad... I need this space to live, and I don't really want to give it up." My second thought was "Crap, I'm going to die," which was shortly replaced by "no, actually, I'm ok as long as I don't fall over." Somehow I managed to find my horn, and stay on it as he collided with my arm. He realised what was happening at this point and moved back into his own lane, and I opened my throttle and got out of the way. I slowed down to sit next to him at the next set of lights, and he sounded rather shaken, so I made sure he was ok and then took off. Didn't muck around after that - I split past every car that gave me room until I was at the front of the row and stayed there until I got to the office. I've only been riding for a few months, but right now I really appreciate all my years of driving and the way I've trained myself not to react emotionally to anything that happens on the road. Can't always control what other people do, but if I hadn't kept my head I'd be lying on the side of the road waiting for an ambulance now instead of sitting here. Anyway, I'd better get back to work.
