I had a similar incident and I'm sorry to say it turned out for the worse for me. I was in a petrol station waiting in a queue for my turn in the car wash. As the car wash kept packing up, running, then stopping, then restarting again, I decided rather than be late for work I'd leave my place in the queue and get going. Because the queue was quite long this idiot in a flash car decided he'd cut in front of the people already waiting and jump in my space. Unhappily I hadn't quite left my space, so he scuffed his front bumper on the side of my car. I thought it would be a simple case of claiming against him, as I was moving forward and he hit me. Oh no! He was with Direct Line and I was with the Halifax - the claim and counter claim went on for a year - in the end my insurance company decided, totally against my wishes, to agree 50/50. Bang went my no claims even though it wasn't my fault. This idiot didn't care, his was a company car. I later learnt that I could have appealed to the ombudsman, but by then I given up.
