The biggest problem I have with SUVs is their impact on my vision and general size. Do you have to park at the end of the aisle in a parking lot, go down the middle of the aisle or roll four feet past the stop line on the street when I'm trying to turn?
Dammit!
In my past experience, I've found truck and SUV drivers to be less considerate -- although now that they're getting so ubiquitous I haven't found that to be the case in the last couple of years... but I still find a bit of recklessness in many truck drivers come winter, thinking four-wheel drive will allow them to tear down the road at dry-road speeds regardless of conditions.
I think a lot of SUV drivers have status on their mind, not utility (or sports, for that matter) -- and in those cases they're wasteful, but what a person does is their business... I think if people at large thought about their consumption, we could do a good job scaling back energy use, but if it takes a spike like this to make the question even relevant to most people, it'll take even more IMO, to create a significant impact on usage patterns.
Although it does bring me to my big complaint about SUVs and gas: it does grate when these same SUV drivers then moan about the price to fill up their tanks. If it costs you that much, you knew it was a fuel hog before you bought it. Suck it up.
In light of this gas crunch, I have read some neat stories in the news -- some guy in Vancouver apparently bought an SUV, took it home, did the math, then took it back the same day. What surprises me is he went and bought a Smart car.
Another touching story I read was about what people were saying at the pumps. In between the bitching and moaning, there was a guy who was filling up a Hummer, and he didn't give a damn. Turns out, he bought the Hummer because it was a shared dream for him and his son to ride like kings in this big thing. Apparently his son was terminally ill and the guy said something to the effect of "I want us to have the best damn time we can together while he's still around." Can't fault that.
Anyhow, there's a point somewhere maybe in the ramble above....
