The New York Times reports that high gas prices are causing people to buy smaller cars.

Soaring gas prices have turned the steady migration by Americans to smaller cars into a stampede.

In what industry analysts are calling a first, about one in five vehicles sold in the United States was a compact or subcompact car during April, based on monthly sales data released Thursday. Almost a decade ago, when sport utility vehicles were at their peak of popularity, only one in every eight vehicles sold was a small car.

Colour me amazed. But it's not too late to interrupt this alarming trend. Let's try a gas-tax holiday. (One question about that proposal, by the way, I wish somebody would put to Hillary Clinton and John McCain: if it's such a good idea, why do it just for the summer?)
