The National Highway Traffic Safety Administration (Nhtsa), the US government agency that deals with road safety, has opened a formal investigation into Tesla Autopilot, the level 2 partially automated driving system of Elon Musk’s electric car company.
The agency, in a statement published on its website, believes that Autopilot has difficulty recognizing vehicles in emergency stop. Since 2018, Nhtsa has identified 11 incidents in which Tesla cars with Autopilot or Traffic Aware Cruise Control (Tacc, the cruise control system that is part of the Autopilot package) inserted have hit stationary vehicles, signaling the their presence with the lights on or the warning triangle. The survey concerns the Model Y, X, S and 3 produced from 2014 to 2021. It involves 765 thousand cars, almost all sold in the USA. After the news, Tesla’s stock nearly 5%; in the last month it has gained 6%, since the beginning of the year it is down by 1.6%.

The US government has opened a formal investigation into Tesla’s partially autopilot (autopilot) system after a series of 11 crashes with emergency vehicles, resulting in one death and 17 injuries. At the end of June in China, Tesla had been forced to carry out a software update on 285,000 vehicles, almost the entire production of a year. Sudden accelerations, due to the lack of an acoustic warning for the activation or deactivation of the TACC, had caused some drivers to lose control of the vehicle.
