there was a programme about speeding recently where amongst their stats of unacceptable behavior there was one along the lines of 78% of people think its acceptable to break the speed limit while overtaking, implying this was wrong. in the same programme a driver got stopped and warned for doing 33mph in a 30 as the road was a bit damp, the copper was going on about how he expected the driver to be doing around 27-28 in those conditions and next time he may do him for driving without due care and attention or some thing similar.
