My fellow idiot American will be back in their cars once the price of gas goes down...and back to buying big, galumping exSUV's. Fools...

Human instinct, like that of all animals, is to conserve energy whenever possible.  That's the main reason people love cars; it's physically much easier to drive than to walk or bike, and it's still easier than taking public transit.

The problem is that humans have been far too successful for the good of the rest of the planet, and without exercising some constraint on their behavior will continue to pollute everything, destroy ecosystems, and force species to extinction.  This is what a real leader would be telling people.  Instead of real leaders, we have politicians who do nothing but pander and appeal to the lowest common denominator.  McCain is worse than Obama, but they both make me sick.
