Mine is not a Tesla, and its range is exaggerated… Or at least its range has a hidden asterisk that would read “under ideal conditions with a gentle driving style.” It self-adjusts based on my recent driving history, and I mostly don’t let the battery get low enough that I have to care about how precise it is… But it definitely skews heavily optimistic, especially when I first bought the car. It’s roughly the same in that regard as a Tesla is, according to the Tesla drivers I know.
