It just gets baked into the resale price. Some EV’s will still have 80% of their range at 20 years and other will be at 50% in 7 years based on owner behavior, battery chemistry, etc.

Though I doubt your friend’s situation would be much different with an ICE. The only way a new battery isn’t covered by the warranty is if he’s already driven 150k miles before 30% degradation hit, at which point ICE cars also see a dramatic drop in resale value.

As to ~10k to replace a battery, high mileage ICE engines end up needing a lot of work over their lifetime. Many 300k mile car see several sets of spark plugs, various belts, plus some big ticket items like transmission, catalytic converter, or cracked head gasket etc. Batteries just condense all that into one big ticket item which slowly degrades and people can budget for.
