I haven’t heard of an epidemic of people dying in NYC by slipping and falling. Walking to the train is perfectly doable — most people where I grew up did it, and I didn’t hear of anyone dying. But there are fewer fats around NYC than in the rest of the US.
Icy sidewalks are why we have laws requiring sidewalk clearance. If sidewalks/bike lanes are not treated on par with streets for cleaning, you’re preferring cars over humans. Which is a problem in itself.
And you don’t carry the bags of groceries by hand. You either dump them in a backpack or use a folding cart.
No one dying here either. You just need proper tires for the bikes. Yep, they make little snow chains.
