Life didn't stop for me when it snowed last year.
Yes, I stayed at home, but I still worked.
there's a few things to remember though, firstly, we do get a different kind of snow, we never get soft or powdery snow, we pretty much only ever get a wet icy sludge.
secondly, we only get that for a few days each year, so nobody is used to it, nobody has practice driving in it, and pretty much nobodies car is suited to driving in it. (with appropriate tyres/ride heights/4wheel drive etc.)
if we had snow all year, we'd get used to it. we'd drive in it and life would go on, since it's more of an adverse condition, it's treated as such... I don't see the problem with that.
in the more northern parts (e.g highlands) it snows a lot more, and people are more suited and adapted to it with appropriate skills and vehicles to cope.
