The fact that the average person in the U.S. is responsible for emitting more than twice as much greenhouse gas as the average person in the E.U. and Japan doesn’t seem to affect their vehicle purchasing or driving habits like you’d think/hope it would. Climate change, dying planet, future generations having to deal with the consequences… who cares. Gas is cheap so lets buy gas guzzlers and drive more! All people who drive, especially those who drive gas guzzlers, should make a serious effort to carpool.
