Recently, Audi is looking to change that with a new stop light detection technology that communicates with specially equipped vehicles to tell the driver exactly how fast to drive to avoid getting caught at a red. Audi installed special devices at 50 traffic lights in Ingolstadt, Germany with sensors that calculate your current speed and the distance to the light to determine what adjustments are needed to lay off the brake pedal. The result is improved fuel economy and CO2 emissions, optimal use of time spent on the road and less wear and tear on the brakes. The system can also adapt to traffic patterns to minimize the amount of red lights you'll have to encounter on your daily drive.
