> The slower turning side creates more friction because it grabs the ice, the faster side glides over rather than grabbing.
For surfaces that do not melt to create a liquid film, this intuition is wrong. If any sliding is taking place, then static friction has been overcome, and kinetic friction is at play. Dry surface kinetic friction doesn't increase with speed: well, the coefficient doesn't but the actual force does!
