I support drilling in ANWR but am against MANDATORY requirement to raise the average miles per gallon.   I prefer to let the market decide.   With the current cost of gasoline, SUV and Hummer sales are down while hybrids are up.    The market will raise the average mileage by iteself.   

Companies that invested in hybrids will prosper.   Companies like GM that put all their eggs in SUV's will falter.    To me capitalism is working very well in this area.
