This is not a former Tesla engineer. This is competitor who wants to discredit Tesla and sell its own solution.
The guy behind this is known to be untrustworthy, and many of the videos don't actually do what he claims. Notably he refused to release the videos that would prove his claims right.
The reality is that Tesla scores high on all the automated breaking test done by government. The driver however can override this, and that is exactly what is being done in this video.
So they scored high on whatever version of software was on the specific car tested by government at some point in time. Has any government done any testing at all on the version of software actually in use today?
The automated breaking is standard part of the software on every Tesla and is the software that was tested by multiple governments. This gives you certification. If Tesla would change or remove that software, it would be highly illegal. Tesla is actually notable that they are one of the only company that has implemented the highest standard of this safety feature on every car. These features are something Tesla is proud of have talked about quite a bit. They also mention that they have achieved the highest scores these evaluations.
The test done above has been replicated and the car does break in automated driving. And it gives loud warning to the driver even under normal driving operation and does emergency breaking.
Tesla assumes that if the driver hits the accelerator after the warning, the drive wants to accelerate based on the drivers judgment.
This is what this video shows, notably the person that made this video has refused to release prove that the car actually was in Autopilot, refused to provide evidence that the driver didn't hit the accelerator and refused to provide audio from inside the car so it can be verified that there was no warning sound.
In addition to that, the same person also claims things like 'millions of people will die if Autopilot isn't stopped' and that even under absurd assumptions is a legit insane thing to say.
So what is more likely, that Tesla did something incredibly illegal removing and incredibly important safety critical software that is standard in every Tesla OR that a competitor is doing a PR campaign where they deliberately set up a situation to film a video where they can create maximum damage to Tesla and then advocate for their own solution.
