I'm wondering why it's not a function of tire slip vs distance traveled. If your GPS says you traveled further than your tires rotated, you're on a slippery surface and need to change driving tactics. Notify once, not constantly. Or turn on a dash icon. (Or leave me the hell alone; I learned to drive under such conditions and I can figure it out myself, thanks very much.)
As to cold being a factor... ice at -40 is not slippery; it can be downright sticky.
