This will never work in New Jersey. I'll tell you right now. People are too in a rush to get anywhere and there are way too many people on the road for everyone to start driving like turtles in order to save gas. Having school buses pass you and not accelerating and not braking and taking your time? The video I saw online with the 2 guys in Toyota Prius' say we are supposed to drive our cars like a roller coaster? How is that safe? We are basically being told to drive recklessly then. Well, that doesn't happen in NJ or any over populated city or state. In Jersey, it would never fly with people here. Everyone is in too much of a rush to take their time. Nice concept if there wasn't so many people in the world but it will never happen. You'll get some that will follow it but never forget that road rage is very big here and in large cities all over the world. Is it safe to offset saving a few bucks in gas for the lives that some people will take because they want you out of the way for driving too slow? Everything in society is built and made to go faster… Cable, internet, faxes, e-mail, even CARS! the list goes on and on. Now you want people to drive like they have no where to go? HA! Good luck with that one. You want to know how to save on MPG's? How about taking the expensive ethanol out of the gasoline. It's an added expense and all it does is make your gas burn faster.
