Fatal accident in Tesla in 2016: the Autopilot partially blamed by the NTSB

For the NTSB, Tesla's Autopilot system did not fail, but lacked safeguards to force the driver to comply with traffic and hand-holding obligations on the steering wheel.

 In 2016, a first fatal accident in California led the National Transportation Safety Board (NTSB) to investigate the role played by the Tesla vehicle's Autopilot driving assistance system.

At the end of a lengthy initial investigation by the National Highway Traffic Safety Administration (NHTSA), the NTSB report concluded that the Autopilot system, which includes an adaptive regulator and a queuing and automatic line changeover system the main axes, was not directly involved in the accident by having functioned correctly and within the limits of its capacities.

 The Authority, on the other hand, is concerned about the lack of measures to force the driver to keep his hands on the steering wheel and to remain attentive to the surrounding traffic and the fact that it was possible to activate the Autopilot mode on tracks which were not made for him.

The report notes that the system for detecting the presence of hands on the steering wheel constitutes an insufficient device to ensure the attention of the driver in the context of a semi-autonomous system which requires the maintenance of the driver's vigilance.

The manufacturer Tesla has always protected himself by recalling the limitations of his Autopilot system but the experiment logically showed that the safety instructions were quickly forgotten by a certain number of drivers.

In the case of the accident in 2016 in California, the Tesla driver would have had time to see the heavy goods vehicle engage and slow down accordingly if it had been attentive to the traffic, but the report also notes that 


the driver of the truck did not leave a sufficient margin of safety when maneuvering on the track.
 In this context, the wrongs are shared, but it appears that the Autopilot system was then used on a track for which it was not designed and the absence of strong restrictions on the operation of the Autopilot outside the intended framework is probably one of the causes of the crash.

Since then, the Autopilot system has been reinforced with new procedures and additional sensors, including a front radar in addition to the cameras that could have prevented the accident.
