Not everywhere is San Francisco. Where I live, it's below freezing almost half the year. No one wants to add bike lanes that will only get lightly used 3 months a year.
Scandinavia, The Netherlands, London, Paris. Great for cycling, shit weather.
Buy a coat and some gloves.
Denmark has excellent bike infrastructure and terrible weather.
I bike 9 to 10 months out of the year in southern Wisconsin. It would do people well to get outside and spend less time on their screens in the Winter.
