This article is about "testing" conducted by a guy who is trying to sell competing software products and has produced videos in the past that weren't replicable and were likely staged. They never release unedited footage or car diagnostic data, just a produced video presented with the intent of damaging Tesla's reputation and boosting their own sales.
This happens all the time, from the New York Times' false claims that their review car ran out of charge, to the most recent Mark Rober video that cost the CEO of a lidar company his job.
The video in this article requires independent validation it is not from a trusted source as it is produced by an extremely biased and financially motivated Tesla competitor.
