Yes, I agree. But it's close enough to a wash, since most planes carry cargo, and most drivers don't take a family of five.
I think on average driving is probably a little more efficient but not by a large margin. Not enough to justify a three-day road trip over a three hour flight (unless you're on vacation and want to see the scenery).
