Car hacking remains a very real threat as autos become ever more loaded with tech

Should you be worried about a car being hacked? USA TODAY's Jefferson Graham and Chris Woodyard break it down. Model cars run in a city miniature at the Elektrobit booth to show how software for highly automated driving works during CES 2018 in Las Vegas. Automakers and suppliers are making progress in protecting vehicles from cyber attacks, but the car-hacking threat is still real and could get increasingly serious in the future when driverless vehicles begin talking to each other. A worst-case scenario would be hackers infiltrating a vehicle through a minor device, such as an infotainment system, then wreaking havoc by taking control of the vehicle's door locks, brakes, engine or even semi-autonomous driving features.
