I’m also involved in the electric Smart community and those batteries have phenomenally low degradation, often being above 92% at 8 years, due to excellent thermal and charge management.
The only manufacturer that seems to put their money where their mouth is in Hyundai with a lifetime length and mileage battery warranty.
Another example: iPhones have a 1-year warranty but usually last much longer than that.
iPhones are irrelevant to the discussion, lol.
No, it's not. That's why some manufacturers offer much longer warranties than others despite having similar reliability numbers. Warranty terms are driven by the business and encompass a lot more than mean time to first failure.

If warranties were a good approximation of how long things last without repair, why would that only apply in the car world?
What's an example of this controlled for the price of the car?

Warranties are a good approximation in the context of cars. Virtually all other consumer devices have a 1 year warranty so it's not really a distinguishing feature.
In any case, warranty aside the reason I even brought it up is because many manufacturers warranties imply potential for up to 30% degradation after about 8 years which is why I used the numbers I used (https://www.recurrentauto.com/research/how-long-do-ev-batter...)
> needing any repair
But for the battery, you were talking about when it needed replacement.
Any decision to offer a warranty beyond that is driven by whether it will entice new car buyers to buy the car or to pay more for it.
