Well with 1 ticket in 27 years and my Average Consumption showing between 41-45mpg per week on general town and A roads driving, does that sound like I have a lead boot on my right foot ?
My mates reckon I'm bordering on Driving Miss Daisy material

That's another thing...41mph in a 30 limit. That sounds almost reckless...but the other side of the roundabout is exactly the same wide open ground and is a 40 limit.
If I knew how to post an image I'd post one from Google Earth. Then you'd see what I mean about the built-up area behind whilst the camera concentrates on the wide open, dead straight, un-obstructed 30 limit.
Don't get me wrong, exceeding the speed limit is speeding...end of chat, but why are they ignoring the residential area behind the camera van ?? There is over a mile of houses with front doors that open directly onto the pavement. If a child ran out of one of those houses, the width of the pavement is all that seperates them from the road.
