NHTSA Investigating Potential Tesla Autopilot Crashes That Left Two Motorcyclists Dead NHTSA Investigating Potential Tesla Autopilot Crashes That Left Two Motorcyclists Dead In the midst of an already ongoing investigation into Tesla''s Autopilot and Full-Self Driving claims, the NHTSA is now investigating two new accidents involving Teslas that took place over the last month. The Tesla''s were "apparently running on Autopilot", according to APs coverage of the story . The accidents wound up killing 2 motorcyclists, the report says. The NHTSA is now looking at whether or not Tesla vehicle automation stops the vehicles for motorcycles. Both accidents were similar in nature: the NHTSA said it "sent investigation teams to two crashes last month in which Teslas collided with motorcycles on freeways in the darkness". In both instances, the motorcyclists were killed. The agency now has suspicions "that Tesla’s partially automated driver-assist system was in use" during both accidents. The first accident was at 4:47am, July 7 on State Route 91, on a freeway in Riverside, California, the report says.
