I think part of the reason that America is not higher is because our population is not as old as some of the other countries on the list. Europe is a lot closer to zero population growth, so more old people, more people with licences, more drivers, and more cars. As much as America thinks it has got it bad with the Baby Boomers it seems Europe faces a much bigger problem.
Though, by my logic, Japan should be much higher up on the list.
