Tesla Driver Died Using Autopilot, With Hands Off Steering Wheel 0

A week after crash, company says it recovered computer logs

Driver received several visual, one audible ‘hands-on’ warning
Tesla Inc. confirmed the Model X driver who died in a gruesome crash a week ago was using Autopilot and defended the safety record of its driver-assistance system that’s back under scrutiny following a fatality.
Computer logs recovered from the Tesla driven by Wei Huang, 38, show he didn’t have his hands on the steering wheel for six seconds before the sport utility vehicle collided with a highway barrier in California and caught fire on March 23, according to a blog post the company published late Friday.
“The driver had received several visual and one audible hands-on warning earlier in the drive,” Tesla said in the post. The driver had “about five seconds and 150 meters of unobstructed view” of the concrete highway divider and an already-crushed crash cushion that his Model X collided with, according to the company. “But the vehicle logs show that no action was taken.”
The collision occurred days after an Uber Technologies Inc. self-driving test vehicle killed a pedestrian in Arizona, the most significant incident involving autonomous-driving technology since a Tesla driver’s death in May 2016 touched off months of finger-pointing and set back the company’s Autopilot program. A U.S. transportation safety regulator said Tuesday it would investigate the Model X crash, contributing to Tesla’s loss of more than $5 billion in market value this week.
‘Mushy Middle’
“This is another potential illustration of the mushy middle of automation,” Bryant Walker Smith, a University of South Carolina law professor who studies self-driving cars, said in an email. Partial automation systems such as Tesla’s Autopilot “work unless and until they don’t,” and there will be speculation and research about their safety, he said.
Tesla defended Autopilot in the blog post, saying a vehicle equipped with the system is 3.7 times less likely to be involved in a fatal accident. U.S. statistics show one automotive fatality every 86 million miles driven by all vehicles, compared with 320 million miles in vehicles equipped with Autopilot, according to the company.
Devastating Event
“None of this changes how devastating an event like this is or how much we feel for our customer’s family and friends,” Tesla wrote, pushing back against criticism that it has lacked empathy by bringing up safety statistics to counter past scrutiny of Autopilot. “We must also care about people now and in the future whose lives may be saved if they know that Autopilot improves safety.”
Tesla has introduced driver-assistance features through Autopilot that the company continuously improves via over-the-air software updates. While the company said as of October 2016 that it was building all of its cars with hardware needed for full self-driving capability, it hasn’t said when its vehicles will clear testing and regulatory hurdles necessary to drive without human involvement.
The U.S. National Transportation Safety Board sent investigators to look into the crash. The agency and the National Highway Traffic Safety Administration also are examining a Jan. 22 collision in Los Angeles involving a Tesla Model S using Autopilot and a fire truck parked on the freeway.
NTSB Findings
The NTSB concluded in September that Autopilot’s design was a contributing factor in the 2016 fatal crash in Florida involving a Model S driver who’d been using the system and collided with a semi-trailer truck. The agency criticized Autopilot for giving “far too much leeway to the driver to divert his attention to something other than driving.”
In the wake of that crash, Tesla updated Autopilot to stop allowing drivers to ignore repeated warnings to keep their hands on the wheel.
While the NTSB also criticized partially autonomous-driving systems that only monitor steering wheel movement and don’t measure whether drivers are looking at the road, Tesla hasn’t adopted or enabled scanners that can track whether drivers’ eyes are looking ahead toward the road.

A Timeline of the Tesla Autopilot Crash Investigation 0

March 23: Walter Huang, a 38-year-old Apple Inc. engineer, dies after his Model X crashes into highway barrier in Mountain View, California.
March 27: The NTSB sends two investigators to the crash scene and notes on Twitter: “Unclear if automated control system was active at time of crash.”
March 27: Tesla releases its first blog post, “What We Know About Last Week's Accident,” saying it hasn’t been able to retrieve computer logs from Huang’s vehicle and blames the damaged highway safety barrier for the severity of the crash. Tesla also claims the U.S. government found a year ago that Autopilot reduced crash rates by 40 percent, a characterization of data from a National Highway Traffic Safety Administration report that some safety experts call misleading. “Out of respect for the privacy of our customer and his family, we do not plan to share any additional details until we conclude the investigation,” Tesla writes.
March 30: Tesla releases a second blog post late on Friday night that acknowledges its driver-assistance software, Autopilot, had been engaged at the time of the crash. “The driver had received several visual and one audible hands-on warning earlier in the drive and the driver’s hands were not detected on the wheel for six seconds prior to the collision,” Tesla writes.
April 1: An NTSB spokesman tells reporters that the agency is “unhappy with the release of investigative information by Tesla.” The agency’s protocols require companies who are a party to an agency accident investigation to not release details about the incident to the public without NTSB's approval.
April 2: Tesla CEO Elon Musk discusses the investigation on Twitter:
April 9: NTSB discloses agency Chairman Robert Sumwalt spoke to Musk over the preceding weekend. An agency spokesman said Sumwalt described the conversation as “very constructive.”
April 10: Tesla puts out a statement that faults Mr. Huang and denies moral or legal liability for the crash.
April 11: Tesla says it has withdrawn from its party agreement with the NTSB: “We believe in transparency, so an agreement that prevents public release of information for over a year is unacceptable.”
April 12: NTSB releases a statement saying it had removed Tesla as a party to its crash investigation. “The NTSB took this action because Tesla violated the party agreement by releasing investigative information before it was vetted and confirmed by the NTSB.” The agency also releases a letter from its chairman to Musk.
April 12: Tesla releases another statement, again claiming to have withdrawn from its agreement with the NTSB.
