I'm hoping that my car's battery only lasts for 7.9 years. It has an 8 year guarantee :D

Then I'd get a new one and my car would be practically new for 8 more years.

You'll more likely get a refurb that fills up to 70% of rated capacity. I own a Tesla and that is Tesla policy.

I don't own a Tesla and it's not Hyundai policy to give refurb stuff.

On the battery too? Good to know.

"But I still trust in people's capacity to digest being utterly wrong ­— eventually."

It always comes back to diet, doesn't it?

I actually believe the claim in the study to be true. But it’s also a terrible design - there’s survivorship bias in selecting operational batteries. It’s not clear if you are thinking that much more carefully than the self-made expert, even if you think you are :)
