The Weirdly Complex Science of Snow Removal

I always thought that not plowing the streets in residential neighborhoods was a genius way to keep people at home on snow days, at least before everyone and their brother decided that owning a pickup truck or an SUV made them invincible.

But cities put a real effort into clearing snow from the streets, starting with the main thoroughfares and places like hospital entrances.

Streets like the one to my house usually have to wait at least until the temperature rises, and by then the problem is solved on its own.
