And I'm not sure how an indication that a Tesla has been tested (and retested) invalidates a claim that 15-20% of all cars are tested. There have been dozens of Tesla models over the years, one would expect at least a handful to have been verified. Which by the way would have totally sufficed to invalidate the original argument; the ranges are largely self reported, but they do get checked. The process ensures that the ratings broadly reflect EPA's testing methodology, otherwise you'd see the cars that do get tested having abnormally low range at best, and fines and other action taken by the agency at worst. A Wikipedia link might be a crappy form of "proof", but as near as I can tell the parent post just made up how he or she thought the process worked. If someone says Caesar lived in the 9th century, a link to the relevant page actually is a valid response. If that person comes back with some source material that says otherwise, then you'll need to try harder.
