There’s more and more evidence that $4.00 a gallon gasoline is the magic number for getting Americans to cut back on fuel consumption.

In April, Americans drove 1.4 billion fewer highway miles than they drove in April of 2007.

And things are trending to even less driving with the drop in April being three times greater than the drop in driving between March 2007 and March of this year.

The question is, if gas were to decline back to the $3 range or lower, would Americans keep up their new habits or would we all revert to using as much gas as we please?
