The Tesla Design X in the Mountain See crash also collided with a Mazda3 and an Audi A4, before the batteries burst into flame
The report into the March 2018 crash that killed Walter Huang has blamed a litany of failures in Tesla’s Autopilot technique for the deadly accident.
Huang was killed when his Design X veered into a concrete barrier on the central reservation of a Mountain See road. Huang experienced earlier complained to his spouse that the Tesla experienced a inclination to veer to the crash barrier at that place.
“Process overall performance details downloaded from the Tesla indicated that the driver was working the SUV using the Targeted traffic-Mindful Cruise Control (an adaptive cruise management technique) and Autosteer technique (a lane-maintaining aid technique), which are highly developed driver support techniques in Tesla’s Autopilot suite,” the report states.
The investigation also reviewed earlier crash investigations involving Tesla’s Autopilot to see whether or not there have been typical difficulties with the technique.
The NTSB results and recommendations on the deadly Walter Huang crash are now readily available (PDF listed here: https://t.co/ERvmDSho26). Below are a couple of what I think are the most consequential:

In its conclusion, it uncovered a series of basic safety difficulties, together with US freeway infrastructure shortcomings. It also determined a larger number of difficulties with Tesla’s Autopilot technique and the regulation of what it referred to as “partial driving automation techniques”.
A person of the most significant contributors to the crash was driver distraction, the report concludes, with the driver apparently running a gaming software on his smartphone at the time of the crash. But at the exact time, it adds, “the Tesla Autopilot technique did not give an effective indicates of checking the driver’s degree of engagement with the driving process, and the timing of alerts and warnings was inadequate to elicit the driver’s response to prevent the crash or mitigate its severity”.
This is not an isolated trouble, the investigation carries on. “Crashes investigated by the NTSB [National Transportation Basic safety Board] continue on to present that the Tesla Autopilot technique is getting made use of by drivers exterior the vehicle’s operations design area (the situations in which the technique is meant to operate). Irrespective of the system’s recognized limits, Tesla does not restrict wherever Autopilot can be made use of.”
But the primary induce of the crash was Tesla’s technique alone, which mis-read through the road.
“The Tesla’s collision avoidance aid techniques have been not created to, and did not, detect the crash attenuator. Due to the fact this object was not detected,
(a) Autopilot accelerated the SUV to a better velocity, which the driver experienced beforehand set by using adaptive cruise management
(b) The ahead collision warning did not give an alert and,
(c) The computerized unexpected emergency braking did not activate. For partial driving automation techniques to be safely deployed in a superior-velocity working environment, collision avoidance techniques should be ready to successfully detect opportunity hazards and alert of opportunity hazards to drivers.”
The report also uncovered that checking of driver-applied steering wheel torque is an ineffective way of measuring driver engagement, recommending the enhancement of better overall performance requirements. It also included that US authorities palms-off solution to driving aids, like Autopilot, “primarily relies on waiting for problems to occur somewhat than addressing basic safety difficulties proactively”.
Tesla is one particular of a number of manufacturers pushing to create total car or truck self-driving know-how, but the know-how continue to stays a very long way off from completion.
