i used to ride my bicycle every day but during the winter i decided not to get squashed by trucks and started walking instead (the sidewalks didn't get cleared, so i couldn't bike on them and i absolutely wont share an icy road with cars).

If you have some disposable income I cannot recommend studded bicycle tyres enough here. I mean the slippey-slidey-cars are still a (potential) danger but having car drivers gawk at you like you're walking on water because you're riding a bicycle at 30° corner leans on iced out roads is fun
