Here is a demonstration of audi’s auto piloted system. The have equipped one of the from factory Rs7 with a few extra camera’s and sensors and send it out on the track with no driver. It may not be the fastest or take the best line all the time but it is no slow poke either, reaching speeds over 150 kph all with no one behind the wheel. To see the action skip to 2:20 in this video, or listen to some of the technology they put in the car.
