> American cars are so inefficient. They don't have to be -- the Chevy Volt (Vauxhall Ampere) is one of the most efficient cars on the planet, and is designed and manufactured in America (including the battery).

For some, it's a badge of honour to have a car that's really huge (SUV moms) or loud and spitting out smoke (Muscle Cars / Pickup Trucks), as a cultural identity statement.
