I've gone for the dashcam approach, which was a difficult choice since I'm not a fan of the UK massive over surveillance society. Many months ago I reached the point where I decided if it's needed I'm going to have my own footage to the police. The final straw was a cyclist a few months back who ran a red light at a 4 way junction attempting to pass between me and the car in front, who were the 4th and 5th cars of a stream going through a green light at around 20 mph. Having managed to avoid him (fab response from the guy behind me), bike guy then wants to get into it, yelling he is gonna call the poilce. He seemed a bit taken aback when I said, 'ok go for it, I'll wait right here'. Naturally at that point he proceeds to ride off, threating me with this and that.. Sure, the junction had CCTV all over it and red light cameras, so if it had gone bad in the end I would have been ok...but... I have no interested in waiting 12 months paying for lawyers waiting to be proved correct. I wanna get that sorted out 5 mins after the event, as I'm sure most people would. I'm not on a tirade again bikes here, that was just the final annoyance. Could be a car, bike, or a horse for that matter. I drive all over the world and in some crazy places, however imo the UK is one of the most agreesive places to drive right now. For me it was time to take a proactive and protective approach.
