Dangerous driving? [Control Software]

The paper mentions that hackers could take over a car´s control networks with potentially fatal consequences.In the real world, a hacker would first of course have to get past a modern car´s access security systems programmed ignition keys, alarms, immobilisers and so on. Even then there is the moot point of whether it´s actually worth the bother of hacking into a single car. The focus of concern is a modern car´s Controller Area Network (CAN), a vehicle bus standard that allows the car´s 70 or so electronic control devices to communicate with each other without the need for a host computer, and to which the OBD port is connected.
