Imagine, if you will, never having to stop at a right light ever again. Oh what a world that would be! But while the folk at Audi haven’t quite managed to retro-fit the planet to stop every single red light that might ever be, they have managed to completely rethink how we approach them.
Setting up tests in Berlin, Verona and Las Vegas, these geniuses have hooked up a specific Audi A3 to a high percentage of each city’s traffic light systems via the on-board wi-fi system. From there, thanks to the simple heads-up display on the dashboard, your car can feed you information about the upcoming set of lights. If it’s going to stay green, the car will tell you the optimum speed to sail on through. If it’s going to turn red for less than ten seconds, the car will keep the engine running. If it’s longer, the car will switch off its engine and turn it back on five seconds before you need to move.

Audi claim that these minor changes will cut back on 15% of CO2 emissions and 900 million litres of fuel in Germany alone, as well as easing up on congestion within these busy cities. So while it might be a while before Audi, and individual cities, get around to hooking this system up to every car and every set of lights, it does make the future of driving a little bit brighter.
