Having a camera might make no difference to the incident or an actual collision, but it could make a huge difference in the aftermath. Other road users can lie pathologically to avoid taking any blame. I've direct experience of this myself, and the camera sorted out the truth rather nicely.
Worth having it just for that I suppose. I am now slightly concerned about being blamed for something I didn't do - I've been sat here all day wondering about what if I had hit him.
As I remember it also helped out Bollo a couple of years ago. The oncoming volvo that turned straight across his path, infront of witnesses?
If I remember correctly, he tried to blame it all on Bollo, denied what the witnesses said, till the coppers said "Have you seen whats attached to the side of his helmet?"
