Agreed. My wife has an 80 mile round trip commute each day and the gas prices have not hit us that badly because her car gets great mpg.
You got it right. My wife has an almost identical commute. Her 2007 Toyota Corolla gets 42mpg (commute is essentially all "highway driving"). When we bought her Toyota, I got rid of my Ford Ranger, which was getting 24 mpg, and took her "old" car (1993 Acura Integra), which gets 32 mpg (highway miles). "My" commute is about 2 miles each way--- :^).
