This video aligns with my experience. The highways around me in the Western Rockies are plowed 24/7 in the long winter but the bike paths end up with 2+ feet of snow/ice on a warm day and upwards of 5 feet in blizzards/squalls and the snow trucks only make it worse. People ride their snowmobiles on the bike paths in the winter. Nobody rides their bike on the highway in the winter as cars/trucks rarely slow down and the wall of snow made by the snow trucks don't give the bicyclists anywhere to go.
Can't even bike safely in the summer in my smallish city in Canada. No bike paths, with roads that keep getting wider with increased speeds, such that the city recommends riding on the sidewalk, and then you are supposed to dismount to cross the road every block. Cycling in Los Angeles where near misses were a daily occurrence felt safer.
