A few days ago at temp traffic lights which had just gone red, I filtered up the inside to the front of the stationary queue of traffic and placed myself just in front of a white pick-up, so I could be seen. When the lights went green I shot off and had cleared the lights on the other side controlling that traffic flow, when the pick-up started tooting at me from behind. I glanced round to see gesticulations from the driver's cab. The next thing I knew, he tried to crush me into the kerb, but overshot because I expecting this and stopped dead. He mounted the kerb just in front of me and I swerved round the rear of the vehicle and went on my merry way. He then overtakes me again and about thirty yards ahead stops, gets out of the cab and takes a swing at me as I cycle past. I duck, he misses. I'm already repeating his number plate to myself and stop 100 yards further on to enter it into my mobile. As I'm doing this, a driver of a back transit stops and offers to be a witness - very kind of him and I gladly take him up on the offer. We exchange details and after, I pedal off to the Police Station to report the incident. The upshot is that The Police are coming round on Friday afternoon to take a statement. I hope they decide to prosecute, But I'd just like to ask the driver of the pick-up: WHY?
