I learned to drive in 63, and the instructor insisted on taking me out on the ridgy frozen slush roads and learning to cope. Not much opportunity to practice since, and you are right, there are many muppets, who have never driven on the stuff. Some drive very cautiously, others overtake on the bus lane from Bluewater. Someone's gone into the barrier on the way up from the place. Not down! I stay off the roads as far as poss, because of them.
