Allow me to add to the stereotype, though, it seems to be rather thruthful around this way....
Funny that you mention minivans, because around this way, they drive like they are late for a funeral. Wait, let me back up a sec.... in general, just about anything around here that eats up gas, less than 20mpg, drives like it has been stolen. I swear, and because of this, the next time I hear someone who owns one of those things complaining about gas prices, I am gonna happily wear the silver bracelets for punching them right in the mouth. It's not so much that they own the thing, I don't care, but seeing the way the majority of them drive around here, their driving is hardly mpg friendly anyways.
My WReX is rather aerodynamic being the '06 hawkeye design. At highway speed (55-75) there is nil drag that I can feel affecting my momentum. But then, a giant Tahoe flies by doing 75+ considering I am doing 75. We all have seen the brick design of those. Can you imagine how much more drag that thing is fighting compared to a more aero, lower profiled vehicle? Let alone how much more fuel is being BURNED to fight that drag?
But, I am not just gonna pick on the SUV and minivan owners. Considering some clown in a '04 STI was speeding through traffic today on the highway on my way to work. I could see him for about 6 miles shucking and jiving through traffic.... and in the end when he finally caught me, it looked to be all just to catch up to give me a wave. C'mon man. It seriously ain't worth all that.
I tell ya, if mother nature doesn't kill us all off, driving will.
