Probably a silly question

I’ve seen a bunch of posts and comments over the last few weeks talking about getting a few last drives in before garaging the car for the winter.

Any reason so many folks don’t drive their 944s in the winter?

Edit: I’ve gotten some good answers, thank you! As simple as it is snow, ice, and salt didn’t cross my mind because I live in the southeast and winter is generally mild, it snows once every few years and never sticks, and we don’t use salt on the roads.
