Ever since I've fallen twice on black ice in past 4 years cycling in winter, I've been way more conservative of when I will go cycling when there's snow /ice on pavement.

I wish I wasn't but I especially think about this if I am riding on the road with cars around me. I want to be certain I can ride safely without alot of icy patches along road sides which is often.

Maybe it's getting slightly more whimpy as I get older.
