The amoubnt of disruption is more about transport than people not wanting to get to work, in 1962 when we had a really bad 6feet of snow, my dad dug a path 100yards long to get us to the main road to school. But in 1962 people didn;lt travel far to work like they do now, many people walked or biked it, and certainly didnlt have to travel in their own cars, cos very few had cars.
Now you have to think about the hazaed of maybe having an accident and being carless whilst it is fixed.
