In fact I believe the odometer reading is calculated from the electricty consumption, not from a meter in the gearbox. So if the range reading is inaccurate (and they are) it would throw out the mileage as well.
Should be super easy to prove too… Take an assortment of Teslas to a 1 mile stretch of road, drive it up and down 20 times, measure the mileage before and after.
Not necessarily, the incorrect readings may only occur at certain speeds or conditions.
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.
