What I don't understand is why today's cars don't get much better gas mileage. My old 89 Cavalier Z24 with the 2.8 and 5 speed would get 33 mpg on the highway easily. There aren't a whole lot of V6 cars today that truly get 33 mpg on the highway and they all should. Cars got bigger and people got power hungry. And they are all pedal to the metal and slam on the brakes when they get to a light. As for shutting a car off at a light, no way I would do that. Starting a car is the worst thing you can do so why do it more than you need to.
