On Monday, the National Transportation Safety Board met to discuss its investigation into the March 2018 crash that killed Tesla owner Walter Huang. The hearing followed a recent release of a trove of documents related to the investigation, which revealed that Huang had in the past repeatedly experienced the same glitch that caused his Tesla Model X to veer out of its lane and into a concrete highway gore, as well as the fact that he was playing a game called Three Kingdoms on his iPhone in the minutes leading up to his death.
The NTSB also had to reiterate a number of previous safety recommendations. Once again, it asks the NHTSA to develop testing standards for forward collision systems, including at high speed. Such systems are only fully effective below 30mph (48km/h), although in part this is because of the physics involved in slowing a vehicle sufficiently after a threat has been detected. Additionally, NTSB again asks the NHTSA to come up with a way of verifying that automakers have equipped their cars with safeguards to prevent driver assists like Autopilot from being used outside the conditions for which they were designed.
