Tesla odometer uses “predictive algorithms” to void warranty, lawsuit claims (arstechnica.com)

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.

That would make no sense. There has to be something spinning connected to something rolling in the ground.

All the AC motors have some kind of encoder to control rotation (and can easily be used to count rotations as well). But if Xitter and Doge have taught us anything, it’s that the programmers for Musks companies more not be very competent.

Apparently its based on the field rotations in the motor or something, remember this is a fixed gear vehicle. I don't think ICE cars use a gear either anymore, its based on the crankshaft sensor for the EFI, multipled by a gear ratio figure in the ECU. Even pushbikes don't have gear sensors for speedo reading, they count magnetic fluctuations in the rim.
