As another comment mentioned, the cited studies are more about how the battery chemistry changes over time, not how people use the EV. That said, EV manufacturers definitely care about driver habits too, since it affects warranty claims and how they configure their battery management systems.

I think modern EVs are set up to charge to a certain percentage of capacity rather than a specific range, kind of like how smartphones do it.

Your point about depth of discharge ( 80%->17% ) makes sense though, since the battery system can't really control someone's driving routine.
