Palut, if the person going 80 would slow to 70, BOTH would get even better mpg. No need to worry about gasoline useage so much, as long as you don't mind subsidizing the sellers of oil as much as we currently do. Me? I do what I can to lower my useage...I hate to think about the people that are getting all the money (and what some of them are doing with that money) for what would otherwise just be black goo.
