what? no they don't.. This is completely dependent on where you live. In stockholm, absolutely the roads are kept clear first in many areas, as well as the rails with plow trains. Then they have plows for the sidewalks. In Ursvik it was certainly the case that they kept the roads clear first
Not to mention many kommun areas' snow are managed by its citizens (t.ex. the areas southwest of Farsta Strand). It's not uncommon that areas don't get plowed at all and people just chance driving it.
Blatant exaggeration of limited cases where this is true imo.
