I'm going to be more prissy about snow or ice on the ground but less prissy about low temperatures.
When there is snow or ice on the ground, there is also slush and snow and ice of many various thicknesses and textures. These blobs jut out into traffic, and dodging them and going over them is tricky in traffic. There is no tire that can handle all of these textures. And riding in that mess takes too long.
But when it's cold and dry, I hope to keep moving. I have a ski helmet, and that turns an unpleasant ride into a pleasant one.
