JackH wibbled...[QUOTE] Bit harsh... aren't they normally supposed to give you the benefit of 10% of the speed limit + 2mph doubt?[/QUOTE] IIRC it's down to the regional force, most do, some don't, I think in the end it's the decision of the plod on the day. I was on the bike, straight A road, behind 3 cars and 2 lorrys doing 40ish, overtook them all and as I accelerated past them all, got clocked as I was passing them. Wasn't taking the piss either.
