not quite sure where your coming from here, I too saw a few accidents, mainly low speed fender bumps, but some people will drive out when conditions are poor (i know some have no choice, but many do.) Some of the driving skills on show were terrible, people going way to fast on hills with approaching corners, heavy braking, to high a gear, not being patient, or giving space to others, the list goes on. I even saw people driving up to the moors 275 to 350 metres, 6 inches of snow, with semi blizzard conditions, and NOT in a four by four, I,m mean why risk it, take the main roads instead. As for schools being shut, well lets get real, in these modern times it seems any excuse to shut a school, some even shut with just 2 to 3cms, I dont know how they would of coped in the 70s or 80s when snow was measured in good old feet and inches
weather is weather, what about fog, or heat waves in summer, all potentially more dangerous than snow, or wind storms.
