I understand the argument now thank you. And I guess that makes sense for people stuck in that positioning, they would have to be marketed to with guarantees to change their mind.

Or, what I suspect but have nothing but anecdotal data - the “25k replacement” positioned group is not that big, or not big enough for manufacturers to care. I’ve certainly never heard that as a fear or even mentioned from anyone I know. Manufacturers can probably just ignore these folk, sell to the rest of the market, and over time they’ll change their mind “for free” anyway as more mass market evidence comes in of it not being a real problem. Or not, and they never sell to those particular folk, but oh well, it’s still not worth it, it’s incredibly expensive to change a skeptics mind. These companies aren’t idiots, they do all kind of market positioning research. The fact that there’s no product/guarentee for your particular concern probably means it isn’t worth it to them. They’ll never get your $ but they don’t care.

I do idly wonder if there’s a market here for a specific insurance product for ev batteries, and then those that have the fear can buy it.
