Was it you on Friday morning on one of the roundabouts for an A5 junction in Bletchley/MK. You arrived at the traffic lights to be level with a grey Evo. That was me driving. Sorry for not looking over, I was deep in thought then wondered why my car started making a funny noise (must be as the scoob arrived). I only noticed what the car was when I pulled away, or I would have waved.
