holy shit... somebody doesn't drive in the mountains much in the winter...
if the roads get to the condition where you need chains or studded tires to get around it will most definately get closed.
Even in the worst conditions with winters and Quattro I still see people in dodge caravans with 1,000,000 mile all seasons managing to make it through the mountains.
The guys in the ditch are almost always 4x4 pickups or suv's that are driving like retards. Very rarely is it the guy in the Chevy Malibu.
