I understand all the frustrations that extreme winter conditions bring.
I have flown and driven all around the very north of Sweden and Finland during winter.
The fact is these place expect such conditions every year, and get them. It's predictable.
The key factor is that they spend the needed money to keep things moving. They have the money, equipment and technology available spefically.

We could do just the same in UK, but would we all be prepared to pay the extra money for that? Would it be a worthwhile cost?
