Being new to this whole commuting by bike stuff I've been reading these pages avidly. Bad and abusive behavior by drivers sounds like assault to me. Even accepting no actual physical violence happens (which would be battery) I wonder whether we should simply report it to the police every time it happens. I'm thinking of a standard letter to the local nick with details of the license plate number, then a campaign via CTC or LCC to get the blues to take notice. even though I havent even taken my first ride I'm thinking of getting a video camera, or having a still camera with me to photograph the car and driver. or am I just being naive?
