I think you greatly overestimate how many 8-10 year old EVs will actually require replacement batteries. Barring a few models with poor engineering choices, most cars will still have 80% of their capacity after 10 years and won't have the downsides of having a 10 year old ICE engine with a variable record of maintenance.

EVs that are 10 years old now will have a lower range than current models, AFAIK, so 80% of that might still be limiting. They will also be slower charging.

  Very true on both accounts (I own a 12-year old Tesla) but for vast majority of EV owners this is simply not an issue.

    Do the vast majority never drive a long distance? If you use a car purely for short journeys maybe. Is this common in the US? Everywhere I have lived most people do atleast some long (i.e. an ICE car needs refuelling at some point) some long trips.

      I have friends with an EV that just rent an ICE car for road trips.

        exactly this. EVs are definitely not for road-trip-every-week families, I rent a car 4-5x per year (my other car is EV as well)

Is an EV with 80% battery still usable? I ask because phones with 80% batteries are practically e-waste, or urgently needing a replacement. It's not a fair comparison but that degraded battery in a phone is a problem, because the phone still requires a certain amount of power that the battery now struggles to provide and overheats, in many cases, causing secondary damage to other components (like the display).

  Phone batteries have relatively little margin. If it lasts barely a full day at full capacity, going down to 80% means you can no longer reliably say "I'll charge it overnight". A car battery that lasted 300km new but now only 200km is still entirely adequate for a commuter with a 25km typical commute, and occasional 75km days out.
