It's likely there were indeed people who felt that way about traction in the snow being improved with "2 wheel drive" vs 1WD. Especially if they were running snow tires in the winter, which was common in those days.

Pontiac didn't call it "Saf-T-Track" to imply that it was good for the drag strip

With the wrong tires, though, both wheels spinning just means you go off the road sideways much more quickly. Have seen plenty of that in my years of living in the snow belt, too!
