Never have to stop again at a red traffic light. That will be enabled in future by the new Audi car-to-X application.
It connects the car with the central traffic control computer, which controls all the traffic lights in the city.
Based on that information it shows the driver what speed needs to be selected to pass through the next traffic light through a green phase.
This is seriously clever stuff, imagine how much less stressful your morning journey to work would be with this bad boy as a passenger, awesome.
