Autopilot was engaged during deadly Tesla crash in March

More first responders need to know how to handle battery packs after they have been badly breached and I wouldn't be surprised if the report finds that the driver would have likely survived if the crash attenuator was fixed before the crash. He was transported to a hospital but died from his injuries later that day.

In the report released Thursday, the NTSB said the SUV was operating with traffic-aware cruise control and autosteer lane-keeping assistance engaged at the time of the crash. It is not a driverless system but is often treated as one by drivers.

"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. The NTSB says it now will examine the cause of the crash.

Walter Huang was fatally injured when his Tesla Model X P100D slammed into a previously damaged crash attenuator on Highway 101 in Mountain View on March 23.

The Autopilot system was engaged on four separate occasions during the 32-minute trip, including continuous operation for the last 18 minutes and 55 seconds prior to the crash.


The NTSB reports no pre-crash steering or braking occurred, and the system did not instruct Huang to put his hands back on the wheel. The auto gave Huang two visual alerts and one auditory warning to place his hands on the steering wheel during the trip, though those alerts were made more than 15 minutes before the crash. It is unclear why the alerts did not continue. The car's computer didn't sense his hands on the steering wheel for six seconds before the collision, according to NTSB. A Tesla website says its vehicles have "full self-driving hardware".

The interior of a Tesla Model X 75D semi-autonomous electric vehicle is shown in January 2017. Uber had deliberately disabled the emergency breaking system on the vehicle, the NTSB found.

"At 3 seconds prior to the crash and up to the time of impact with the crash attenuator, the Tesla's speed increased from 62 to 70.8 miles per hour, with no precrash braking or evasive steering movement detected", the NTSB found.

Seven seconds before the crash, the Tesla, still following the vehicle ahead, "began a left steering movement". Four seconds before the crash the Tesla wasn't following a vehicle any more. But the safety device had been smashed 11 days before by a Toyota Prius. "The focus is on what led to this crash and how do we prevent it from happening again". The full investigation can take as long as two years to complete. They differ on whether Telsa was pushed from the inquiry. At this point, the NTSB has yet to determine a probable cause of the crash and is continuing to investigate the accident.

The Tesla continued traveling through the gore area until it struck a crash attenuator, which was mounted on the end of a concrete barrier, at a speed of approximately 71 miles per hour (114 km/h).
