Why does no one talk about what happens to the car after its effective useful life? Is it because the battery in the car is far worse for the environment than the car was ever good for the environment during its active useful life. These multi-thousand dollar batteries have a very long decay life. We will be long gone before these batteries will.
Nope. The batteries are no problem. When they reach the end of their useful life they automatically turn into rainbows and carbon free unicorn farts.
I seem to remember reading an article a few years ago that we dump the batteries in India for reclamation. I could be wrong though.
