One reason SUV's are often taxed higher is due to their higher ground weight. A Hummer or a Chevy Suburban does more damage to roads than a Jaguar sports car. They're both paying more in gas taxes because they use more gas than the majority of vehicles, which I doubt most would have a problem with. Heaver vehicles cause more wear and tear on the infrastructure than smaller, lighter vehicles. So I totally support a higher registration on those vehicles. They cause more surface maintenance issues. To be honest, I doubt that most people who drive SUV's have a need to load three adults, a dialysis machine and a dog into it every single day. Many of us need to stop buying vehicles for what they "might need." (I'm not necessarily saying that is your case, Python.) Just because a person hauls the boat to the lake or river once a year and puts it in, doesn't mean they need to drive a vehicle that sucks 14 mpg all year round. Just because they live in an area where it snows, doesn't mean they need four wheel drive. I grew up in southwestern Minnesota on the snowy, wind-whipped prairie, and got by just fine with my front wheel drive Geo Prizm. I personally cannot fathom any reasonable explanation for someone who lives in a city (or really, anywhere else) to drive a Hummer. Unless they are a wilderness safari tour leader on the weekends. Hmm...don't know anyone like that.
On global warming...our honorable (? Ok, not my favorite) congresswoman, Michele Bachmann, got roaring laughter when she used dubya's line, "the jury's still out on global warming" in a debate. That might be out on Youtube somewhere.
Yay for us for getting out of our cars and onto our bikes. Now plant some trees. Spend the money to get the efficient light bulbs and appliances. Lobby your city for pedestrian and bike friendly development. Plant a community garden and get your neighbors together. Put a receiver hitch on your car and pull a small trailer on those days when you need to haul something. Heck, go in on one with some of your neighbors.
Getting off my soapbox now.

"I rejoice every time I see a woman ride by on a bike. It gives her a feeling of self-reliance and independence the moment she takes her seat; and away she goes, the picture of untrammelled womanhood."
Susan B. Anthony, 1896
