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.
There isn’t any way you can make a Y/3 much cheaper, its an inherently expensive design, being essentially a cut down Model X. The fact that they lack the resources to make a new platform seems telling.
