Today's new cars come equipped with dozens of microcomputers connected by a network and run everything from infotainment systems to the engine itself.

Imagine this grisly scenario: You're driving down the interstate with the cruise control set at the speed limit. Without warning, your car accelerates. The speedometer pushes past 100 miles per hour. Suddenly, the car turns left and crashes into the concrete median.
