There are smaller snowblowers for clearing sidewalks. They usually make a pass before the street blower, to the snow gets piled up in the parking lane or car lane to make it easier to remove.
People need to get used to the fact that snow is a common and normal thing in North America. Either you fit threads and skis to every vehicle, or you get the proper equipment to get the snow out of the way.
Snowblowers cost much less than the impact of having to close things when there's a big storm.
