The biggest concern is inter-connectivity. If auto manufacturers could figure out that all the systems DO NOT need to be intertwined with core functions (steering, acceleration, braking, engine management, etc) this would not be an issue. It's one thing to mess with someone's stereo, it's a whole other when they can get access to the CAN bus and drive your car into a wall.

Granted they are not releasing the code that allows a hacker to get access to those systems, these guys are just 2 of thousands with the skill and expertise.
