How high? Apparently, 65 percent of respondents agreed that "the government should increase the fuel economy standard to an average of 50 miles per gallon by 2025," according to CFA Director of Public Affairs Jack Gillis. As of right now, the U.S. fleet averages roughly half that lofty figure. As pointed out by the boys at Green Car Advisor, such a drastic increase in fuel efficiency "would save more oil in two years than all the proven oil reserves in the Gulf of Mexico." Kinda puts things into perspective, no?
