On Tuesday morning, Senators Ed Markey and Richard Blumenthal plan to introduce new legislation that’s designed to require cars sold in the U.S. to meet certain standards of protection against digital attacks and privacy. The legislation, as described to WIRED by a Markey staffer, would call on the National Highway Safety and Transportation Administration and the Federal Trade Commission to together create new standards that automakers would be required to meet in terms of both their vehicles’ defenses from hackers and how the companies safeguard any personal information such as location records collected from the vehicles they sell.
