My commuter (Ford Fiesta) gets an overall long term ave of 37.7mpg. I have a Ford pickup that gets 15mpg but doesn't get used much. We pay about $1USD/gal in federal taxes, really not much compared to other countries. Part of the drop in oil price is the drop in demand in the states. Wages are still pretty stagnant, so you use less gas anyway you can. Years ago I drove my truck all the time. No more!
