Having read through the tripe that is the first half of this thread, I have only this to say: THHHPPPPHTBT!! [Ack! Thhbbt!]
SUVs are a trend. Fortunately, trends are ephemeral. Unfortunately, "large cars" are a
cyclical trend. Same thing happened 25 years ago, until Darth Nader shook his fist and wagged his finger and made congress give in, creating new legislation on emissions, pollution, car size & safety.... [See:

Nader was a whack job. Touched in the head. But a whacko with a conscience. See, he gave a damn about the potential damage human existence can do to its environment. As has been already said, large vehicles require large engines; large engines require large amounts of fuel; mass consumption of fuel creates spoiled deserts, greed, CO, CO2, benzene, toluene, formaldehyde, methyl tertiary butyl ether (MTBE) [See:
http://www.aqmd.gov/news1/In_car_facts.htm], soot, acid rain, and contributes greatly to various wars and skirmishes.
Per mile traveled, an SUV consumes far more fuel and creates far more pollution than your average grocery-getting econobox. This wouldn't be a problem except for the fact that more SUVs are replacing those econoboxes...and all they're doing is getting groceries. Of course, SUVs are not polluting at a 2:1 ratio (or anything near it) compared to cars. It's more like 1.4:1, but that's still pretty bad. Expect to see another round of anti-pollution, anti-everything-fun legislation, followed by another set of "Dark Ages" for American car companies while they try and figure it all out again. [For a hint on how things affected them and how long it took, look at the specs of the Mustang from 1972 to 1992.] The Japanese seemed to manage quite well last time, and I imagine they'll do well again. European car makers should do well, too; far better than last time.
Buying SUVs is done under the pretense of safety. Similar logic is used by the NRA, where if everyone has a gun, we'd all be safe. [Believe me; me & my temper are the last duo you'd want sharing space with a ballistic weapon, and I'm sure I'm not the only one.] This logic is flawed in the automotive industry: SUVs are trucks. Trucks are tall. Too tall, in fact, to properly match bumpers with even a large luxury sedan. It also rides over the door crash beams. This is where the term "incompatible" comes in. Basically, SUVs are potential (if accidental and totally passive) hazard in an accident with anything other than an SUV. "So why doesn't everyone else buy a SUV?" Erm, why doesn't everyone else buy a gun? [Or maybe it's just not our style.] Granted, we're comparing apples to oranges, but at least they're both fruits.
SUVs can not only be a danger to other drivers, but to the driver of the SUV himself. [Here's where "rollover" comes in.] Trucks are still tall. While the entire vehicle is scaled up in comparison to a car, it's not totally in proportion. The road clearance is higher, as is the roof compared to the floorpan. This makes for a top-heavy vehicle. At low speeds, modern SUVs drive and feel like a car, but this is misleading. At highway speeds (anything over 40 MPH), physics don't kick in, they never left, and high-speed sharp turns mean this thing ain't going 'round nicely.
BTW: "AWD" does not mean "I can drive on any god damned surface however I god damned please". Ice is ice, and unless you have studded tires, drive like you actually give a hoot. Moron.
I am not condemning SUVs. It's certainly not an emissions issue (not with the way I drive my WRX). SUVs have their place. Just not in suburbia. You need space? Buy a nice E-Class wagon. You need to carry 7 kids? Get a Grand Caravan. Want better all-weather traction? Look up Audi, Subaru, Volvo, Mercedes, BMW, or any number of AWD sedan manufacturers. And if you're wearing really short shorts and absolutely need that SUV to fill the void between your legs, get something that won't kill someone: BMW X5 (lack of rollover), Volvo XC90 (total compatibility), or just move to Canada.
