"Tesla, which was overtaken by Apple as the largest U.S. equity short recently, is back on top of the league tables, a position it has held since March 2016", wrote Ihor Dusaniwsky, head of research at S3 Partners, as quoted by CNBC.
Tesla retains its party status in several other NTSB investigations involving Tesla vehicles, including the crash of a Tesla auto that was operating under Autopilot when it drove into a fire truck in California.
"There is nothing in the party agreement that prevents a company from enacting swift and effective measures to counter a threat to public safety", said Sumwalt. In a tweet, the agency wrote: "Unclear if automated control system was active at time of crash".
The issue of driver attentiveness "is really a critical area", said MIT's Reimer, whose team is testing a fleet of vehicles rigged with cameras to observe how drivers perform in real-world situations. The company says it doesn't yet know what happened "in the moments leading up to the accident, and we do not yet have any idea what caused it".
Tesla was unapologetic, however, and insists that it unilaterally withdrew from the agreement. "We don't do that sort of analysis at this point in the investigation".
But then Tesla posted an update on March 30. This reminder is made every single time Autopilot is engaged.
In the post, they revealed that the system showed that the driver's hands were not on the wheel for up to six seconds before the collision and the vehicle's logs indicated that no action was taken, although the driver was said to have received several warnings. It pointed to USA government data indicating that Tesla's Autosteer system, which is part of Autopilot, reduced crash rates by as much as 40% compared to vehicles without it.
"The firm believes Tesla's Autopilot feature is defective and likely caused Huang's death, despite Tesla's apparent attempt to blame the victim of this awful tragedy", the law firm expected to represent Huang's family said, according to The WSJ.
Tesla said that "even though we won't be a formal party, we will continue to provide technical assistance to the NTSB".
After partially faulting Tesla's automation system for a 2016 fatal crash, United States safety investigators a year ago called on carmakers to do more to ensure drivers stay engaged as next-generation cars start to steer themselves.
April 12: exhausted yet?
Tesla Inc. lashed out at the National Transportation Safety Board after the agency took the unusual step of removing the automaker as a party to its investigation of a fatal crash in March in which a Tesla vehicle's "Autopilot" system was in use. We believe this would've never happened had this Autopilot never been turned on'.
Tesla claimed that while there is one automotive death every 86 million miles in the USA, while for Tesla's equipped with Autopilot that number dips to one in every 320 million miles.
Tesla Inc.'s (NASDAQ:TSLA) Model 3 production "Hell" delays are now being dubbed a "time shift", by its CEO, Elon Musk.
It's been clear in our conversations with the NTSB that they're more concerned with press headlines than actually promoting safety. We don't believe this is right and we will be making an official complaint to Congress. Perhaps there is a sound rationale for this, but we cannot imagine what that could possibly be.
Musk has previously griped about the NTSB's involvement, saying it's up to the National Highway Traffic Safety Administration (NHTSA), not the NTSB, to regulate the auto industry.
According to data Tesla gave NHTSA investigators prior to its decision against any recall, Autopilot's steering system may prevent the rate of crashes per million miles driven by about 40 percent, a figure the company cited in its latest statement. The Model X SUV caught fire and the driver died.
