I think they did it with a Fordy Sync system, I believe it was Popular Mechanics that did the demo. They were trying to point out the inherent weaknesses of the systems that combine the entertainment computer systems with the cars engine and systems computers. In the case of the Sync system, the two computers are the same and PM was able to hack into it via a cell equipped laptop and the extent of their control was remarkable. The vehicle did not have electric steer so they could not directionally control, however all throttle and engine management functions could be manipulated as well as brakes and much more. They shut down individual cylinders, applied one or all brakes, affected the light control and a lot more.
