Consumer Reports characterized this year’s North American International Auto show as “the rise of the mainstream plug in hybrid,” foretelling a definite trend that’s emerging among automakers: fuel-efficiency is becoming the name of the game.

This is great news for the environment, and for consumers, but with the vehicle fleet becoming more efficient in the USA, a probable negative consequence may emerge along with it. Specifically, as cars become more efficient, there will be less funding for mass transit infrastructure – an unfortunate systemic outcome indeed.
