They are better at snow driving
I'd like to see a statistic that shows what percentage of the US has persistent snow (say, 24 hours).
The main issue is that AWD/4WD in sedans isn't that common, while they're nearly standard on an SUV. But that's a matter of market dynamics (people think that SUVs are required for this sort of driving, which is laughable), not any inherent technological or cost limitation.
