Another one is why do people do 40/50 in a 60? where i live in derbyshire they have just put the speed down on most of the good roads from 60 to 50 A515, Snake pass, cat and fiddle (the last two have been like that for a couple of years) and quite a few others. This has now made the speed of traffic about 45 cos people don't want to get cought speeding. Yet all the way along these roads you have narrow single track roads with national speed limit signs on, where's the common sense in that
