There's also a nonzero risk to health while commuting. It seems like for every big snowstorm there is at least one multicar pileup with injuries or worse thanks to people having to commute when its unsafe. I bet if you limited travel during snowstorms to emergency related jobs only, pileups would be a thing of the past because there just would never be enough cars sliding in one place to even pileup.

This is a great point. Commuting to work by car is by far the most hazardous thing most office workers do all day. I bet remote workers have a measurably higher life expectancy purely from the reduced commute-miles.
