I stay in Boston, and winter really isn't as big a problem for public transport as people make it out to be. I can't think of many cities outside Canada/Russia that have worse weather (cold, high precipitation and windy).

If anything, owning a car in the winter is a massive pain as driving is riskier, involves daily drive-thru shovelling and regular de-icing that gets irritating rather fast. Biking does get quite difficult for longer trips, but people still use bikes (owned or rental city bikes) for short distance trips to the grocery stores within 10 minute distances.

I recognize that this only works in dense enough cities. But, if the city is dense enough to have good public transportation in the summer, then it is dense enough for public transportation to be sufficient over the winter.
