[quote="IainG"]I thought a speed limit was the maximum speed permitted, not the only speed permitted!
As I campervan driver, it's quite entertaining to watch the mad rush to get past slower vehicles before the dual sections end.
I have always had a sneaking suspicion that drivers of large camper vans, caravans and old men in hats driving at 40mph whatever the conditions get some sort of perverse pleasure from holding everybody else up. I think everybody (and that includes the dodderers) should drive with a bit of consideration for everybody else. If you are causing a huge tail back because you can't or won't drive at a reasonable speed you should pull over and let people pass. After all, as you say, what's the rush?
