While I don't dispute EV depreciation (it's a fact, no matter the explanation), then I don't think depreciation is as "huge" of a factor as you make it out to be. People buy new cars all the time, while the added utility over a used car is negligible.

I.e, I've only bought cars that are 10+ years (exactly due to the depreciation factor!), but most other people buy or lease as new of a car as they possibly can afford. Doesn't make financial sense to me, yet it's done so very often.
