Auto manufacturers, technology companies, road safety advocates and policy makers will attend a March 1 conference over potential government actions that could speed the rollout of autonomous cars, the U.S. Transportation Department said on Friday. Reuters reports: Next month's "summit" is to help "identify priority federal and non-federal activities that can accelerate the safe rollout" of autonomous vehicles, the department said. It will also be open to the public. The U.S. National Highway Traffic-Safety Administration (NHTSA) wants comments on what research to conduct before deciding whether to eliminate or rewrite regulations. It could take the agency years to finalize rule changes, and advocates are pushing Congress to act. The March 1 meeting at the department's headquarters in Washington will include "several stakeholder breakout sessions on various topics related to automation," NHTSA said.
