DETROIT (Reuters) - There's a simple way to get Americans to drive fuel-efficient cars, according to auto executives, but they are not going to like it -- sharply hike the gas tax.
While politically unpalatable, gasoline that costs at least $4 a gallon would have a far greater effect on American fuel usage than Washington's $25 billion loan program meant to spark investment in new technologies, executives told the Reuters Autos Summit in Detroit.
