So, here we go.... Hacker city. Especially any .gov who wants to play god and off someone. Like they likely did with reporter Hastings who was working with Snowden. They took his C250 and and overran the following systems: steering, braking, engine management, fuel system safety cut off, anti theft, air bags and seat belt tensioners. They used this control to murder him. The car was accelerated to full throttle in LA boulevard, and ran him into a tree at over 100 mph. Shut down all the safety systems, and the car burst into 1400 degree flames with the DI high pressure fuel systems running from the tank.
Two 22 year old kids hacked a Prius, and took a Forbes magazine senior editor on a ride of his life. They showed him what can be done. Steered the car heading to a tree, killed the brakes, doors locks , and kept the car from being shut off. Some cool YouTube videos showing it all. Black Hat folks confirmed. They used blue tooth, Protected WIFI to take over the car.
As they said in the link above, Hyundai will have the cars "controls" and control systems, run by this thing. AND allow remote access.
Unless they offer a X Prize like reward to anyone able to hack the car, and no one is able, who in their right mind would buy this?
