The lead plaintiff in the case, Nyree Hinton, bought a used Model Y with less than 37,000 miles (59,546 km) on the odometer. Within six months, it had pushed past the 50,000-mile (80,467 km) mark, at which point the car’s bumper-to-bumper warranty expired. (Like virtually all EVs, Tesla powertrains have a separate warranty that lasts much longer.)
For this six-month period, Hinton says his Model Y odometer gained 13,228 miles (21,288 km). By comparison, averages of his three previous vehicles showed that with the same commute, he was only driving 6,086 miles (9,794 km) per 6 months.
Edit: I just want to point out that I just learned that changing your tires to ones of a different diameter can also affect how your spedometer clocks. So yeah, this issue is full of nuance and plausible things as to why this could not be true.
Open up your Google Maps (or navigation app of choice) and you’ll likely have a record of how far you’ve traveled within a given time period.
Subtract off any cab rides and rides in friends’ cars, and that’s your number plus or minus some distance in driveways or parking garages that the app can’t accurately measure.

Sure. But then you’re still relying on an accurate odometer. I assumed the question was how you do it when disputing one.
In the case of the article, the plaintiff is using prior vehicle mileage rates as countervailing evidence.

The plaintiff is using that as one piece evidence right now at the start of the case. Of course they can and will gather and present other evidence.
