Driving down the A303 to visit a client I knew that there was sometimes a speed trap at the bottom of one of the steep hills. As anyone who uses it will know, in summer months, it is full of caravans, lorries and VW camper vans. I got trapper for 10+ miles behind a line of such traffic actually being held up by an old boy in a Nissan Micra. The normally slower traffic were actually passing this guy, 1 by 1 and I felt like it would never be my turn; however, just before the hill it was. Knowing the trap may be at the bottom I held back despite the road changing from 1 to 2 lanes. As we got th bottom I saw the old boy in the Nissan get pulled. I actually felt bad for him; he'd probably been doing 20mph under the speed limit all day and thanks to the hill he got pulled.
