My little Scion xB gets awesome gas mileage so it's not too too bad. Gas is around $3.60 per gallon in Phx right now, it usually costs around $40 to fill up my tank and I do that maybe once a week, give or take depending on if I randomly drive to far places much or not. I drive a fair amount so it doesn't seem too bad.
I'm kind of glad I wasn't driving yet when gas was only a dollar or so a gallon, I never had (comparatively) super cheap gas to miss really, to me it's always been expensive lol. Though I'd sure love if it it went back to those prices.
