This is an oddly imprecise position to me. It's unclear whether an 8" snowfall is a natural disaster. In places where this is a regular event, it is not treated as a natural disaster. Some human drivers drive in it just fine, though most prefer not to.
What about a 3" snowfall? That is a more common event, and a much larger number of human drivers stay on the roads despite the snow.
