Not really. Most of the people that are really suffering from gas prices have newer, large SUVs and trucks. They can trade them in on smaller cars that cost less and keep the same payment or even reduce their payments. I also don't know why you would think insurance on a car would be more than an SUV.
As for premium gas prices rising faster than regular... huh? The gap between regular and premium has been steady for a long time. It used to be 10 cents between each grade but it's usually 15 cents now. If regular rises 20 cents, premium rises 20 cents. I've been driving premium only cars for years and I've never seen premium rise when regular did not.
If you're driving a big SUV, the best thing to do is get rid of it when you can. The residual value on them is falling really fast and demand is going down so if you can, get something else. You may take a little negative equity but if you get something less expensive and with much better gas mileage, you can offest that a little and not still hold onto an asset with value that is dropping like a rock. If you can't trade it without taking a really huge equity hit, drive it as little as possible and try to sell it yourself.
