I was half an hour into an evening ride tonight, cycling through Buckland Common when a car started to overtake me, I felt a blow on the the outside thigh. The car was too far away for it to be a collision with any part of the car - the passenger side mirror was at least a foot away from me and the car was not being driven erratically. Fortunately, a pretty light blow and not nearly enough to destabilise me on the heavy steel bike.
I finished my 27 mile ride and worked out that I was cycling in Bucks at the time, so called Thames Valley Police who seemed to take it quite seriously. I've made an appointment to visit their nearest police station in Chesham in Wednesday (I live in Herts).
No chance of successful prosecution, I know, but if these idiots have a go at every cyclist they overtake then someone else will be seriously hurt or even killed.
It spoilt what was otherwise a really nice evening for a ride having to repeat the car registration so I did not forget.
