Agreed. While I do agree with trying to reduce gas consumption, creating a non functional state is not helpful. I would think wasting all these otherwise decent batteries is far more harmful to the environment than the miniscule amount of fuel that is saved.It means they turned OFF the ECU battery monitoring circuit which controls how the alternator charges your batteries (In theory), to reduce emissions and increase MPG. Now... your alternator is constantly charging your batteries (Just like the old days.) In my opinion... I'd rather have a lower MPG that to have a dead battery or No Start issue. Then again... If you can't start your car. The you save MPG because you can drive it.
