JohnJBurnsIII, 
As a few states begin to handle an ice storm... let's provide a few tips:
4-wheel drive does not equal 4-wheel stop!
Spinning tires does not equal traction!
Spinning tires faster makes it worse as tires heat up and melts snow / ice into water. Water on ice does not enable friction to be better.
Best option is to not drive on icy roads.
Of course, the folks who need to incorporate these tips - won't.
