It is a complete waste of gas to stop your car completely at a stoplight when it's just going to turn green immediately. Well, to avoid this hassle Audi is currently testing out an ingenious system.

An ingenious system tells you exactly when lights you're approaching are set to change. The "Travolution" project networks cars with traffic signals wirelessly, showing you exactly when the upcoming light is going to change and how fast you should be going to clear it. This will not only improve fuel efficiency, but it should make traffic flow a lot smoother."
