While Mullaly is correct in arguing that oil imports have only increased since CAFE went into effect, there is also the fact that the standard has not risen since it reached its current level in late 1980s. However, the reality is also that consumers in this country will also tend to buy the biggest, most powerful vehicle they can afford to operate. Why else would F-150s and Explorers outsell by such a wide margin small cars that are and have been available.
Sales of larger, thirstier vehicles have only slackened as gas prices have risen but not nearly enough. Only when the cowardly politicians actually step up to the plate do what needs to be done to address demand for oil with tax changes will the problem really be addressed.
