Consumer Watchdog yesterday formally petitioned the California Department of Motor Vehicles to amend its driverless car testing regulations to require that police investigate any accidents involving driverless “robot” cars. In addition, the public interest group said the regulations should be amended as to require copies of any video or technical data gathered by the robot vehicle related to the crash be provided to the department. Currently, a company whose robot car is involved in an accident must report the incident to the department within 10 days. There is no requirement that police investigate the accident.
