Do SUVs Make You Stupid?

According to Mark Mortford of The San Fransisco Gate ( I assume that's what SF Gate means) driving an SUV makes you stupid.
I don't know about that, but I do know why I drive one. Because I'm scared sheitless of all the fools out there that are diving them too! If that makes me stupid, well heck, I reckon stupid I am and stupid I'll stay. I've been called worse!
