On March 23 of this year, a Model X driving down a California freeway crashed into a highway divider at high speed. Three seconds before the crash, the Model X sped up from 62 to 70.8 miles per hour before hitting the barrier at roughly 71 miles per hour.
Then, seven seconds before the crash, the Tesla began drifting left to align with the lead vehicle as it headed into a left-side exit.
According to the NTSB, the vehicle was following another auto in front of it using Tesla's Autopilot system until about seven seconds before the impact. Huang's hands were detected on the wheel three times in the 60 seconds before the crash, though his hands were not detected on the wheel for the six seconds before the collision. The NTSB had objected to Telsa making statements concerning the cause of the crash before the investigation is complete, while Telsa accused the agency of releasing incomplete information and "trying to prevent us from telling all the facts".
"The consequences of the public not using Autopilot, because of an inaccurate belief that it is less safe, would be extremely severe", Tesla's March blog post said.
Following previous crashes involving Tesla cars, including one that hit a parked police vehicle in Laguna Beach, the automotive company reminded critics its manual says the technology can not detect all objects in a car's path and that drivers should remain attentive.
At the time, a company spokesperson said Tesla meant to file an official complaint with the federal government. Four seconds before the crash it was no longer following the lead vehicle, the NTSB said.

The report noted that at four seconds before impact, Model X was no longer following a auto in front and began to speed up. Recovered data showed that Huang, an engineer for Apple, received alerts from the auto to place his hands on the steering wheel more than 15 minutes before the crash. Just four seconds prior to the impact, the auto in front moved out of the way and the Tesla began to speed up. "Never depend on Automatic Emergency Braking to avoid or reduce the impact of a collision".

In the Mountain View-area crash, the NTSB also is investigating fires that broke out in the SUV's batteries after the crash.
Disagreements between Tesla and the NTSB over the probe culminated in April when safety officials said they had revoked the electric vehicle maker's status as an official party to the investigation.
The National Transportation Safety Board (NTSB) in the States released data extracted from the auto involved in the March 23rd crash.
During the recently-held 2018 Annual Shareholder Meeting, Elon Musk also provided an update as to when Tesla would begin producing the $35,000, standard-range RWD version of the Model 3.
