Audi creates custom A4 slot car track [w/video]
Given how much emphasis Audi puts on traction, the cars were built with special magnets to keep them planted on the track, and each racer was built with a mini camera that can feed images to an iPad wirelessly. Drivers control each car via an iPad app, and the camera feed gives operators an idea of what it's like to drive on the scale creation. Check out a few videos of the track below.
