Could a gas tax revolutionize America?

Will $4.00 make any difference?

A new poll suggests that while $3.00 plus gas hurts, most Americans are getting used to it. And, while $3.00 gas is pushing more to consider more fuel efficient vehicles, it's mostly just causing consideration, not action. Will $4.00 be the magic number to force real change? Will we hit $4.00 this summer?

One thing is for certain. At $4.00 per gallon, there is no question about the cost effectiveness of hybrid cars, which makes me wonder, does this prove a gas tax could revolutionize America?

(Finish: More proof a gax tax could work)
