I've never seen that happen. I have seen it give optimistic numbers, which are dozens of miles short of GPS trip logs, and worse in moderate cold.

When you say "this is information you can trivially look up", not only does this article reference their own testing, but others, and a quick google shows these results aren't abnormal. This article is on the extreme end of test results, but it is not unreasonably so.

Tesla does get a lot of flak, and unsubstantiated fanboyism like this does not help.
