An analysis by a team from the University of California, Davis, MIT and Yale suggests that households that buy a fuel-efficient vehicle tend to compensate for that purchase by buying a bigger, more powerful second vehicle. This unintended effect could erode goals of fuel economy standard policies by up to 60%.
