United States auto safety agency on December 13 said that it will investigate the 12th Tesla crash that may be linked to the vehicle's advanced Autopilot driver assistance system. The agency took the decision after a Tesla Model 3 hit a parked police car in Connecticut recently. The investigation is conducted by The National Highway Traffic Safety Administration special crash investigation program. The team will investigate the December 7 crash of a 2018 Tesla Model 3 on Interstate 95 in Norwalk, Connecticut. Since 2016, Autopilot has been engaged in at least three fatal US Tesla crashes. This development is expected to affect the sales of Tesla cars.
