However what might be worse than Tesla Chinas omission is Teslaratis description of the park button.

Tesla stated that the Park button was indeed pressed during the vehicle’s final drive four times, but only briefly. Previous tests from Tesla owners indicated that pressing Park for an extended period of time while the vehicle is in motion would stop the car. 

First off Teslarati also fails to identify the fact that the park buttons function as an e-brake. But then Teslarati follows it up by saying some users have been able to come to stop when attempting to use the button...but only if held down for extended periods of time.
This description made me assume that the park button simply sends a command to the car to come to a stop and that it had to be held down for extended time to prevent accidental application. That is not the same functionality as an emergency brake. Also per the following video, short presses of the park button while in motion is a method of gradually slowing the Tesla down versus holding the button down for "extended" period of time to immediately come to a stop. I do not know if Mr Zhan knew about this or if his presses of the park button on 4 occasions were consecutive or spread out over time. Regardless the button failed to slow or stop the Tesla. Meaning the signal was either not reaching or being overridden at either the ECU level or computer level.
Is Teslarati responsible for my misconception, certainly not. However my and others misconception was likely their intention by taking advantage of  ignorance of the fact that the PARK BUTTON FUNCTIONS AS AN EMERGENCY BRAKE!!! Or as Tesla calls it, parking brake.
Emergency & parking brakes are essentially a secondary method or system of coming to a stop. For Teslas, it tells the motors to stop all motion. While in motion this is meant to be a backup method of coming to a stop when brakes fail.
Since Teslarati felt it needed to expand on what Tesla China disclosed, it should have been more upfront with its descriptions. As such, their description looks purposefully misleading.

Did you know that your Tesla has an Emergency Brake? Here's how to use it

Driving and car not slowing or stopping
Push on the Park button while car is moving, and brakes will be applied. Like going down a hill too fast. An Emergency.
