Can you find me an example of a modern car that this is true for? I'm one of the few Americans (I guess) who can drive a manual transmission car; I just hate it. But if it were really better for the environment and better gas mileage I would consider it. HN has spurred me to look into it, but the Honda Accord had 1 mpg better for manual, the Toyota Camry had exactly even, and the BMW I looked at had better gas mileage for an automatic. So for now I'm chalking it up as HN'ers being irrationally in favor of manuals because that's their culture (since the U.S. hasn't really woken up yet).
