The Tesla Autopilot Crash Investigation: A Timeline


Tesla Inc.’s ongoing spat with the National Transportation Safety Board over a fatal crash has reached new heights, with the electric-car maker and the safety agency releasing dueling statements. Here’s a timeline of public remarks so far by Tesla and the NTSB.

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:

Elon Musk @elonmusk @TeslaMotorsClub Lot of respect for NTSB, but NHTSA regulates cars, not NTSB, which is an advisory body. Tesla rele…

Lot of respect for NTSB, but NHTSA regulates cars, not NTSB, which is an advisory body. Tesla releases critical crash data affecting public safety immediately & always will. To do otherwise would be unsafe.

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.

“According to the family, Mr. Huang was well aware that Autopilot was not perfect and, specifically, he told them it was not reliable in that exact location, yet he nonetheless engaged Autopilot at that location. The crash happened on a clear day with several hundred feet of visibility ahead, which means that the only way for this accident to have occurred is if Mr. Huang was not paying attention to the road, despite the car providing multiple warnings to do so.”
