As a data point: I’m at year 8 of Model X 100kWh with basically 0% capacity loss. If it exists at all, it’s less than 1-2%, so less than what I can reasonably measure with just the odometer and battery indicator.

Nissan Leaf gave BEV a bad name because it had much worse battery tech. Battery longevity is not a problem for modern, or even decade old cars.
