The NTSB’s main evidence is log details that is saved to an SD Card inside each and every Model X. This details data next-by-next alterations in the vehicle’s steering-wheel position, velocity, and other variables. NTSB examined log details from a month of Huang’s morning commutes and found two days—February 27 and March 19—when the auto drifted toward the lane divider that would eliminate him times later. In every single case, logs exhibit Huang implementing torque to the steering wheel and guiding the auto again into its suitable lane.
Which is not all. A friend of Huang’s furnished the NTSB a screenshot displaying Huang complaining about the issue just after the March 19 incident.
“Do you feel AP [Autopilot] is better?” Hans Ting questioned Walter Huang in a concept on March 19. “I feel it is better … Significantly less jerky.”
Huang responded in Chinese. “Nope, I feel virtually the exact,” he wrote, in accordance to the NTSB’s translation. “Virtually led me to strike the median once more this morning.”
He additional, “Every single time at the 85 separation it would push me to the center of the two traces.”
Nevertheless, the NTSB was not able to ensure a different claim by the family—one that could confirm essential in their lawsuit against the electrical carmaker. Huang’s wife and brother say that he alerted a Tesla consultant about Autopilot’s steering problem for the duration of a check out to a Tesla provider heart weeks ahead of his demise. Information exhibit that Huang did check out a Tesla provider heart to handle a problem with the vehicle’s falcon-wing doors. A faulty sensor had caused a person of the doors to bump into the garage previously mentioned the auto, leading to slight paint harm.
The spouse and children claims Huang explained to Tesla about the problem with Autopilot for the duration of that exact check out. But Tesla has no record of this. Tesla data do exhibit Huang going to a Tesla shop about the door issues. And Tesla’s provider logs exhibit that Huang noted an “issue with GPS/Navigation leading to cruise management to not perform and warn ‘maps not loaded’ to look.”
What that is referring to is not apparent exactly, but it appears like a diverse issue than Autopilot steering into a concrete barrier. An job interview with the staffer who talked to Huang and manufactured that note claims he obviously remembers Huang complaining about the issue with the falcon-wing doors, but he does not try to remember anything at all about Autopilot steering problems.
Huang was Actively playing a Activity on His Mobile phone Minutes In advance of the Crash
Huang labored for Apple, and Apple issued Huang two smartphones. The telephones ended up loaded with improved logging capabilities to guide in troubleshooting issues like memory leaks and too much energy use. Apple assisted the NTSB get better these logs from a person of his mobile telephones, which was seriously damaged in the crash. The organization furnished sporadic but far from thorough details about what software was operating on Huang’s cellphone.
“3 logs recovered confirmed that a activity application, 3 Kingdoms cell edition, was energetic for the duration of the driver’s journey to do the job,” the NTSB wrote in a person of its reports. “The activity is a earth-setting up, method activity with multiplayer capacity. When taking part in the activity on a cell system these as an Iphone eight Additionally, most players have both equally hands on the cellphone to assistance the system and manipulate activity steps.”
At nine:06 am—21 minutes ahead of Huang’s crash—a log entry confirmed that 3 Kingdoms was exceeding its memory limit. The entry confirmed the app to be in the foreground and in energetic use. Then at nine:ten am—17 minutes ahead of the crash—”extremely energetic” use induced a next log entry about high energy use.
The log details suggests that Huang was a regular player for the duration of his morning commute. Log entries for the activity appeared for the duration of Huang’s morning commute on every single of the 4 times preceding his lethal Friday crash.
