You really don’t want that. I mean, if you’re sure things are going to stay below -10°C for the forseeable future, by all means leave the snow on the roads, and I wish more places in Northern Europe would do that. (Winter days become much more tolerable when what little light you have is reflected back by snow.) But if they are not and especially if they are going back and forth, then you’re getting slush, half-frozen slush, frozen slush packed into ice, or half-frozen slush on top of frozen slush packed into ice, and not only do you not want to drive on that, it’s also a pain to remove even from pedestrian paths, because you need power tools to break it up and then you have a crapton of inch-thick sheets of ice you have to transport and dump to melt somewhere. They take a couple of weeks to melt naturally on the road, or a couple of months under the spring sun if you pile them up on the side of the road (which also happens to look hideous).
