Few things are more frightening than the image of an evil genius hacking into a connected car, taking control of the steering wheel and remotely stepping on the gas.
And yet with automobiles increasingly morphing into speeding 2-ton computers, the threat is very real. In July, two hackers proved to Wired Magazine they could break into a 2014 Jeep Cherokee while it was on the highway. That led Jeep parent Chrysler to recall 1.4 million Jeep, Dodge, Ram and Chrysler brand vehicles.
Last month, the FBI released a 2,000-word public service announcement warning of "remote exploits" in motor vehicles. And IHS predicts that by 2022, 73 percent of passenger cars sold will be equipped with an internet-based entertainment portal or web-connected system for things like safety alerts.
