I have owned a Model Y for a bit more than 2 1/2 years, having driven a Nissan Leaf for 8 1/2 years prior. Factoring away the obvious battery capacity difference, I have found the Tesla range estimates to be far more accurate and consistent when compared to the Leaf. While I found the "secret team" headline to be comedic, given my experience with electric cars, I do have other serious concerns (phantom braking #1). Estimating vehicle range using map data is not a simple problem, even if Tesla is utilizing high-resolution GIS data and/or on board accelerometers in their estimating. Weight of passengers, cargo weight, trailer utilization (I just completed a trip through the Cascades pulling a trailer on my Model Y) all factor in, and have larger effects as road grades increase. I think that mileage estimating is a case where Tesla has actually provided reasonable value, but these cars are fallible and far from all-knowing. I recommend developing a cautious range intuition when driving electric cars which may take some time to develop. Honest empathy to those who have been stranded in them.
