SUVs and minivans are both used primarily for one thing: transporting a bunch of kids and all there crap. The stereotypical SUV drivers is a small women with a cell phone glued to her ear and two screaming brats in the back seat. Exactly the same as the typical minivan driver, only generally a little bitchier.
I know there is a small percentage of people who use their SUVs as actual utility vehicles, but that percentage is vanishingly small - kind of like the percentage of serious runners a major road race. If you think and SUV is somehow percieved as manly by the population at large, then you are as diluted as the skinny white boys here who think running is still percieved as a sport rather than a charity parade.
