If you need to bring in graphs to show that someone was going 50 instead of 45 MPH (if the data even matches the speedometer), you've already lost the battle. This is all very aggressive on Musk's part when the overall review still holds up (Tesla cars are bit ahead of the curve for normals). If the log showed gross exaggeration I could see this reaction, but Musk is being a brat and wasting a lot of goodwill. Remember, car reviewers are car reviewers, not QA engineers. Things will go wrong, numbers won't match up exactly. If you want positive coverage, don't post your MPG (or the electric equivalent) with "best case" numbers like a normal gas car. Give yourself some wiggle room. Calling the flatbed tow truck is a pretty bad negative event for a normal car owner who is used to being able to ride on E for a few more miles.
