Tesla Autopilot faces U.S. safety regulator’s scrutiny after crashes with emergency vehicles

The inquiry may signal a new regulatory environment. In June, authorities started requiring manufacturers, including Tesla, to report crashes involving such technology within a day of learning of the incident. On Monday, a NHTSA spokeswoman told The Washington Post that the preliminary investigation will focus on Tesla’s Autopilot system and “technologies and methods used to monitor, assist, and enforce the driver’s engagement with driving while Autopilot is in use.”
