It would take about three months to retool our factories for making cars averaging 35 MPG. We just have GM and Ford import the tooling for the European cars they already make now. Ditto the Japanese, Koreans, Germans, etc, for the cars they make at home.

And suspend the 5 star crash rating system, not to mention the EPA's Clean Air Act.(aka "things European cars don't have")
No problem!

Sure, we'd just use the same air standards as the French and British. After all, they are already fitted with computer controlled fuel injection.

The problem comes down to some of the other provisions in the "new" CAFE rules. There is a significant concern that the laws would push more consumers into buying SUVs and also push the size of the SUVs and other light trucks to be bigger than ever.
