Where was his car parked? Trying to picture it in my mind. Near a Ford and Honda garage is where you are talking about I think? Never, ever seen a speed trap around there.

But if he didn't stop you there and then or other officers there did not stop you and issue you on the spot a speeding ticket, nothing will happen. I never speed anywhere anymore especially on certain stretches on the A10 between caterhatch and M25 junction. Just far too risky never know when the fuckers will pop up!
