You go California: Keep those cars fuel efficient.

With regards to fuel efficient standards, the President wants to make life easier for automakers. The automakers would like that too. The problem is with regards to fuel efficiency and emission standards, California, New York and 11 other states (plus Washington D.C.) have such a large auto market (a third of the countries), that their wanting to maintain high fuel efficiency and emission standards makes making cars less efficient is a cost problem for automakers who can not afford to create two different standards for vehicles across the country.

Continuing to promote fuel efficiency standards and sponsoring the construction of vehicles that carry that out should be continued for the betterment of our country and planet. You can not spend the money if you can not breathe to use it. You go California and the other states (along with Washington D.C.) that are leading the way.
