So not saying this is what the data is saying, but the article is worded in a way that this thought could be true:
What if the reason people aren't replacing the batteries in their cars because they're just selling/trading in their cars? The article doesn't directly say that the first gen cars' batteries are still usable (let's say 80% of "new" capacity), it just says people aren't getting them replaced, which isn't necessarily the same thing.
Does anyone else know any more about this? Its my understanding that an electric car's battery is expected to hit that 80% of new capacity somewhere around the 5 year mark (and as someone who rarely owns a vehicle less than 10 years, that's been a personal barrier to me jumping to EV)
Link to the story (I only read ~25% of article since it matched with my recollection of events)
I leave it as an exercise for you to determine the level of hyperbole your respondee was using.
