WASHINGTON >> Automakers are cramming cars with wireless technology, but they have failed to adequately protect those features against the real possibility that hackers could take control of vehicles or steal personal data, a member of the U.S. Senate is asserting. Basing his argument on information provided by manufacturer, Sen. Edward Markey has concluded that “many in the automotive industry really don't understand what the implications are of moving to this new computer-based era” of the automobile.
