Isn't it slippery?
No. That's what studded snow tires are for.
Do you ride on the road?
Of course.
Isn't is slushy and hard to pedal through snow?
Slush is easy to pedal through. It just oozes and slurps out of the way.
Don't cars slide into you breaking every bone in your body in a cold, wet tragedy?
No. The worse the weather, the more space they give me. Drivers are absolutely terrified of cyclists in the snow. They're scared enough for both of us.

See the tights? My work clothes are in the Tailrider with my lunch. The absolute worst part about winter commuting is putting on refrigerated pants. After that, everything else is easy.
