Cause of Fatal 2021 Tesla Wreck Was “Excessive Speed” and “Alcohol Intoxication”

This was the one where the media reported that because nobody was found in the front seat it must have been the fault of the self-driving feature. The NTSB found that none of the driver-assistance features were activated, and the driver was probably tossed into the backseat from the impact:<p><i>Although the driver’s seat was found vacant and the driver was found in the left rear seat, the available evidence suggests that the driver was seated in the driver’s seat at the time of the crash and moved into the rear seat postcrash. Specifically, residential security video showed both the driver and passenger getting into the front seats prior to driving away from the residence. In addition, the EDR data showed active accelerator pedal inputs consistent with driver activity in the 5 seconds prior to the impact with the tree, and that the driver’s seat belt was connected at the time of the crash. Finally, the steering wheel examination conducted by the NTSB Materials Laboratory indicated an impact to the upper left quadrant, consistent with the driver loading the steering wheel during a frontal crash.</i><p>The entire journey appears to have lasted less than a minute (9:07pm is mentioned both as the time the car left the driveway, and as the time of the crash), so it&#x27;s unlikely the driver jumped into the back seat as a stunt while driving.<p><a href="https:&#x2F;&#x2F;www.ntsb.gov&#x2F;investigations&#x2F;AccidentReports&#x2F;Reports&#x2F;HIR2302.pdf" rel="nofollow">https:&#x2F;&#x2F;www.ntsb.gov&#x2F;investigations&#x2F;AccidentReports&#x2F;Reports&#x2F;...</a>

&quot;Excessive speed&quot; and &quot;alcohol intoxication&quot; -- two common causes of human driver failure.<p>Other causes of human driver failure include driving while tired or exhausted, falling asleep at the wheel, driving while angry or upset, getting bored while driving, using the car&#x27;s infotainment system while driving, using a mobile phone while driving, getting distracted by passengers, smoking pot while driving, being a recklessly immature teenager (or a grown-up idiot), lacking the bare minimum of driving skills that every driver on the road is supposed to have, and so on. The list of causes of human driver failure is long. There are a lot of horrifically dangerous human drivers -- look around you next time you&#x27;re on the road.<p>Notably, machines are immune to all these human failure modes.<p>I&#x27;m looking forward to the day in which cars drive themselves well enough to rid the roads of so much dangerous human driving.

I&#x27;m not sure why they don&#x27;t explicitly write in the report that the driver may have been trapped in the back seat, and was unable to locate or use the mechanical release to escape. While that wouldn&#x27;t be a contributing factor to the wreck, it would be a contributing factor the the driver&#x27;s death, and important for Tesla and their passengers to know about.<p>The report states:<p><i>The frontal impact with the tree resulted in a power loss of the car’s 12-volt system, which runs the non-traction power systems. During normal operation, the front door latches operate electronically with the pull of the interior lever. In the event of a 12-volt system power loss, the interior front doors open as usual using the interior door handles. The rear doors also have both electronic and mechanical latches; however, mechanically opening the rear door during a power loss requires additional steps. According to the owner’s manual, during a loss of 12-volt system power, a rear-seated occupant must locate a small cutout in the carpet beneath the seat cushions and pull the mechanical release cable tab toward the center of the vehicle to manually open the rear door. Inspection of the door latches and locking hardware was limited by postcrash fire damage.</i><p>Edit: Must add that this assumes the front door was jammed and couldn&#x27;t be opened mechanically.

Almost 43,000 people died in car-related deaths in the US in 2021 (and millions more worldwide). I hope we can stop focusing on the small number of deaths from this one car company that has self-driving features.<p>Relevant: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Man_bites_dog" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Man_bites_dog</a>

&gt; the car accelerated from 39 mph to a top speed of 67 mph 2 seconds before the final tree impact, which occurred at about 57 mph. The application of the accelerator pedal ranged from 8% to 98% during the 5 seconds of recorded data, and there was no evidence of braking.<p>My hot take is that it shouldn&#x27;t be possible to accelerate that quickly unless you actually apply the pedal to 100%.<p>Also, I think the accelerator and brake pedals should have a different feel. Maybe they should be made of different materials so there is clear tactile feedback.

The whole idea of being drunk and getting in a car with the intention of driving as fast as possible seems so stupid that I&#x27;ve never in my life even had the smidgen of a thought to do it, even if especially drunk. People really do have different brains.

OT but the NTSB really wants to take the fun out of driving via technology (from the crash report)...<p>&gt;Recently, the NTSB recommended that NHTSA require all new vehicles to be equipped with passive vehicle-integrated alcohol impairment detection systems, advanced driver monitoring systems, or a combination thereof, which are capable of preventing or limiting vehicle operation if driver impairment by alcohol is detected.<p>&gt;A vehicle technology-based solution, such as intelligent speed adaptation (ISA), can reduce speeding. The NTSB has recommended that NHTSA incentivize passenger vehicle manufacturers and consumers to adopt ISA systems by, for example, including ISA in the New Car Assessment Program.

Now I have questions about that seat belt.<p>Especially considering this comment in the report: <i>In addition, the EDR data showed active accelerator pedal inputs consistent with driver activity in the 5 seconds prior to the impact with the tree, and that the driver’s seat belt was connected at the time of the crash.</i><p>So there was a driver pushing the accelerator, wearing a seatbelt (assumption) and ending up in the rear seat behind the drivers&#x27; seat? Did the driver simply plug in the seatbelt without putting it on? Or did the driver survive the crash, get into the rear seat, and was unable to get out in time?

Does NTSB investigate every car crash with a death? Or just Tesla?

I have been critical of FSD marketing in the past. But these kind of accidents could be avoided with self driving tech. I remain optimistic

100,000 crashes per year, I wonder how many the average American thinks there are.

But should the P100D or any other car noted for its sudden acceleration even be allowed to exist? We&#x27;re putting GPS radios on electric scooters so they can&#x27;t exceed 10MPH in school zones, meanwhile drunk bozos can tap 1000HP if they want.

How can a Tesla can even be old enough to drink
