On Tuesday, the United States safety regulator shared that it has sent letters to twelve major automobile companies. It requested their assistance in the inquiry for the accidents involving Tesla vehicles crashing into emergency vehicles while using an advanced assistance system for drivers. The safety agency, National Highway Traffic Safety Administration (NHTSA), asked for data from automobile companies including,- Volkswagen AG, Toyota Motor Corp, General Motors Co, Ford Motor Co, and others. NHTSA asked the automaker companies to share the information on their development and testing of their driving assistance system. Some companies have to respond to the letter by 3 November while others have time till 17 November.

Last month, NHTSA opened an investigation into the accidents involving Tesla vehicles. The investigation report covered eleven accidents in which seventeen people got injured, and one died. Most of these accidents have occurred since 2018 and involve emergency police vehicles. Also, investigation reports suggest that these vehicles were using a driving assistance system during the accidents. The investigation will cover almost all the cars Tesla has sold in the United States since 2014. The approximate number of those cars is 765,000 as per the reports.
Earlier, NHTSA has informed that it will assess the technologies, including the Autopilot system and cruise control function. These assessments will check if the driver assistance system monitors and draws the driver attention while in use. They will also check the functionality of the driver assistance system in terms of detecting and responding to objects and events as well.
