There’s no better feeling for a driver than when you get a string of consecutive green lights so that you can cruise smoothly through the city. Getting a wave of green lights is usually a matter of luck, but Audi wants to make it possible for you every time you drive through it’s Traffic Light Information technology. Basically, the technology combines your car’s position and traffic light data to calculate an ideal speed that shows up on your vehicle’s instrument cluster or heads-up display. In theory, you could save time by driving slower and catching an uninterrupted string of green lights. Although technology is currently limited to Audis in a handful of urban areas, it could soon be something that extends to more cars as we move towards autonomous vehicles.
