It snows in the north. People can often still drive just fine in it. I'd say people should reconsider if they really need drive during those conditions, but I don't think it's right to assume there is no reason at all.

What if someone is at work and needs to get home? What if someone works in healthcare where lives rely on them getting to work? Or any other critical industry energy, heating, plumbing, electrician, etc.?

Just fuck everyone else because there is a slim chance something bad might happen?
