i am seriously hoping that our gasoline burning days are coming to an end. We are just a few years away from an electric vehicle (with gas motor used only to recharge the battery if you run out of the charge the car accumulated from the wall outlet overnight). Even if the green house gasses were not a problem it'd still be a lot cheaper to operate. When those cars become avaliable i will resiously consider getting one...So the fact that I'll be driving a V6 at 23-25 mpg for few more years isn't going to change much.
