We can't yell too much about fuel economy here. True, a high performance Z get better MPG than a Hummer, but not really that much. Especially once you've cammed, tripled 50'ed, 4:11'ed! And I know for a fact this is not the Mild Driver's Club, is it? If this was the Honda Insight Internet Club, we could yell about wasted resources. What offends me about the behemoths is, I live in a crowded city. Baby, we is tight up in here. Parking is at a premium as well as freeway space. And here Joe Somebody in their 6 ton grocery getter as wide as legally possible, taking 2 spaces. F you sir, f you very much, you self centered bastard. I drive an official SUV differential inspector. I can inspect your Hummer for leaks without getting out of my car. God I wish I could see around you on the freeway. If I was a little lower it would not be such a problem as then I could get a good view of the road ahead between your 22'' wheels. I drive a sports car and studied physics. Mass X Velocity = Force is still the rule in my universe. If I perform a high speed avoidance maneuver, I, at least have a chance at making it. Why is this giant truck going faster than I am? Does that driver really feel safer? Dreamer!
