Yes, SUV's make sense. For like the 3% of the population that needs them.

My solution to the SUV problem is to separate all major highways into separate car and truck lanes, complete with concrete barriers in between them. Let the SUV-driving crowd get stuck behind 18-whelers and milk trucks, while I cruise in the car lanes with my Mustang. That way, I can actually see a mile or two ahead of me instead of perpetually having an Escalade in front of me blocking my view.
