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.
Obviously UK consumer protection is different so they may not have the “feature” here, but cars get their milage recorded yearly (after the first 3 years) as part of roadworthiness testing, available online given the licence plate, so I can see I did 7041 miles in the last year.
Does the DMV not have something similar?
I imagine if I looked at the registration of the car it would have that information yes.
