Earlier quoted context omitted.

Also, „hands were not detected“ does not mean that they really weren‘t on the wheel. Maybe someone who drives a Tesla can comment on how reliable the hand detection is.

No idea about tesla, but how do you screw up hand detenction?

The hand not applying any pressure and barely touching the wheel. It happens consistently on my Ford Fusion when I am driving on a straight line. Car says my hands are not on the wheel when they are touching it.

“[Driver’s] hands were not detected on the steering wheel for the final six seconds prior to the crash. Tesla has said that Huang received warnings to put his hands on the wheel, but according to the NTSB, these warnings came more than 15 minutes before the crash.” This kind of stuff is why I’ve lost all faith in Tesla’s public statements. What they said here was, for all intents and purposes, a flat out lie. Clearly…

Add to that, the last bullet point from page 2 of the official preliminary report[1]: 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 mph, with no precrash braking or evasive steering movement detected. That to me is a strong indicator that Tesla's AP2 can not recognize a crashed attenuator, probably one of the strongest argument that…

It reads like he was following another car that was driving at a slower speed but once that car left his path, his car began to accelerate to the pre-set speed of 75mph.

The deficiency of Tesla AP has been abundantly clear to anyone with eyes, for a long time. Only fingers-in-ears Musk fans cannot see that.

This happens with regular adaptive cruise control on my Ford, when the cruise control set point is a lot higher than the current speed: the car accelerates after another car clears the lane and ram into things.

I don't understand why they would issue any statement other than, 'condolences, we're committed to safety, we're working with the NTSB to understand what happened'

Without commenting on the rest of the issues with Musk/Tesla, his tweet about a news verification agency was a joke. Verifiably. It was nicknamed Pravda, and a corporation related to his tweet was registered to Musk on Oct 17 2017, the anniversery of the October Revolution.

A joke? It's verifiable because he said he might name it Pravda, and the fact that he actually registered it is further evidence that it's a joke? I'm not saying he's really going to do it, but I question your certainty here with a total lack of actual evidence.

Reading that initial report is terrifying. I am so glad the NTSB set the record straight that the driver had his hands on the wheel for the majority of the final minute of travel. Really makes me feel like Tesla was out to blame the driver from the get go. To be clear the driver is absolutely partially at fault, but my goodness autopilot sped up into the barrier in the final seconds — totally unexpected when the car has automatic emergency breaking.

Emergency breaking feels not ready for prime time. I hope there are improvements there. Don’t want to see autopilot disabled as a result of this, would rather Tesla use this to double down and apply new learnings.

Just so sad to hear about this guys death on his way to work - not the way I want to go. :(

If I were rapidly approaching a barrier at full speed on a highway, I might put my hands up and guard my face before the crash.

If you were aware of what was happening. Smartphones are distracting.

It doesn't matter if he was following another car or not. If there is an obstacle, AP2 should brake and in that case it should brake hard or use evasive turning maneuvers to avoid head-on collision.

Despite the autopilot failure, I find the battery failure quite remarkable too:

> The car was towed to an impound lot, but the vehicle's batteries weren't finished burning. A few hours after the crash, "the Tesla battery emanated smoke and audible venting." Five days later, the smoldering battery reignited, requiring another visit from the fire department.

Where is your LiPo god now? Batteries have more energy density than 20 years ago, ok. But they are also much more dangerous. Now imagine the same situation with Tesla's huge semi batteries. They'll have to bury them 6ft under, like Chernobyl's smoldering fuel rods. Minus the radiation.
