as with anything, it's not just money. Losing battery capacity in an EV is a hassle. A hassle because you charge more frequently, a hassle because you will eventually need a battery change, and so on. What is the price of all that hassle?

That said, most EV incentive programs use around 10% (often less) of an EV battery capacity so the actual effects are barely noticeable.

> What is the price of all that hassle?

A price that can be measured in money. How much more does it need to pay to be worth any extra hassle?

So in a sense it is just money. Money is hassle, fundamentally. It's a hassle to make it and you spend it to save other hassles.

And since lots of EV batteries seem to lose capacity very slowly after the first 10-15%, and you can keep your battery trading in the happiest range, there's a lot of potential for the extra hassle to be worth the paycheck.
