Something bolder like California's at 35.7 miles per gallon target by 2016 compared to the Bush Administration's 31.6 miles per gallon fuel efficiency standard by 2015 would really have a better chance at bringing oil prices down by effective conservation. In fact the gas prices behind the studies at the Transportation department used a price of $2.86 for the years 2011 to 2015 to calculate the rule's costs and benefits when prices are already at $3.50 per gallon today, so the analysis itself is behind the curve and not upto date. This is not likely to stand the test of time as the whole issue of fuel economy is likely to change as time passes. For instance all the three remaining presidential candidates have expressed support for California's efforts to curb gasoline consumption even with resistance from EPA, and the 2 democratic candidates support fuel efficiency above 35 mpg over time. So its realistic to expect that something similar to the California standards will carry the day as time passes and as fuel economy becomes a real big issue as prices continue to escalate and environmental and other considerations also call for better management of fuel supplies through conservation in transportation not just in the USA but around the world....
