Wonderboy's New Gas Mileage Requirements

Hearing of the new, tougher gas mileage requirements which Wonderboy signed into law this week, my mind went back to this recent post.

Which of the powers granted to the president in the Constitution do you suppose was the one that covers vehicle gas mileage?

I just looked here, and I can't find it. It's not even in the powers granted to Congress. You could try to argue that the interstate commerce clause allows it, but Judge Napolitano would disagree.

Apparently, back in the day, that is, 1789, 'regulate' meant to assure that commerce occurred, with minimal interference, not to micro-manage every facet of interstate business.

This, then, is the sort of federal legislation that leaves you angry over unconstitutional intrusion into private lives and state authority.
