EPIC has submitted detailed comments to the National Highway Traffic Safety Administration, urging the agency to protect driver privacy for "vehicle-to-vehicle" (V2V) technology. The technology transmits data between vehicles to "facilitate warnings to drivers concerning impending crashes." NHTSA is in the initial stages of mandating vehicle-to-vehicle technology. EPIC's comments pointed to several privacy and security risks with V2V techniques. EPIC urged NHTSA to "complete a more detailed privacy and security assessment of V2V communications" and to: "(1) not collect PII without the express, written authorization of the vehicle owner; (2) ensure that no data will be stored either locally or remotely; (3) require end-to-end encryption of V2V communications; (4) require end-to-end anonymity; and (5) require auto manufacturers to adhere to the Consumer Privacy Bill of Rights." Last year EPIC, joined by a coalition of consumer privacy organizations and members of the public, urged NHTSA to protect driver privacy and establish privacy safeguards for car "black boxes."
