WHILE LIVING IN GERMANY, I drove slowly by several high-speed Autobahn accidents involving mangled Mercedes Benz cars. It was unusual to see one explode at high speed and burn like Thermite (as Michael Hastings' car appears) so I'm deeply intrigued by the theory of a car hacking incident.
Former Marine Gordon Duff has shared information about the “Boston Brakes” technique, in which “drive by wire” cars like the Mercedes in the shot, can be manipulated remotely to simulate an out-of-control accident. 
I set up a news alert to follow this story and got some very interesting scenarios from Richard Clarke, the former U.S. National Coordinator for Security, Infrastructure Protection, and Counter-terrorism.  Clarke confirms intelligence services have successfully tested the “drive by wire” concept.  I've used Audioboo to talk about the on-board diagnostic unit and how it's possible to hack one to control a new car.
