I drive a Jeep Wrangler with a 2" suspension lift and 1" body lift with 32" tires, driving a Jeep is already like driving a brick wall, no aero dynamics. Add the larger tires means I get about 14 mpg. Yes, I did this on purpose, and I drive about 46 miles a day round trip to work in stop and go traffic. Trust me, the off road capabilities have come in handy more than once to get around traffic
My wife has a tahoe, it gets about 14.6 mpg. We have one child. Do we need the tahoe, heck yes! We drove to Houston a few weeks ago, and with all the gear we have to carry for our daughter (9 months), we MUST HAVE the extra space. Our bags, her bag, plus the pack n play, toys, diaper bags, as well as my laptop, a bag for our shoes (we put our clothes in duffle bags for short trips) would not have fit in either the Jeep or the trunk of our old car (corolla).
Am I going to apologize for it? No. SUV's are not the reason for dwindling resources. I had a guy tell me that my tahoe was the reason why gas prices were high, then he takes off like a jack rabbit in his little sports car as I slowly drive off. Driving like that burns more gas than my tahoe.
Until we have a new renewable source of energy, we need to be drilling in Alaska, and looking into other fuel sources. I'm rather fond of hydrogen fuel cells myself.
So, yep, high gas prices suck. I knew that when I upgraded my Jeep, I knew it when I paid more to get a Tahoe and I sure as heck know it when I fill them both up. You're not having to pay to fill my tank, so my advice is not to worry too much about what I'm doing, just watch out for yourself, I have things taken care of
