It's clearly not part of the solution as napkin math demonstrates, and that's not even including losses into and out of the batteries, which pushes the numbers into the realm of ludicrous.

If you want to argue otherwise, demonstrate it with an estimate of the energy amounts used.

Because I did the check. I don't think you have.

The energy is used to drive the cars, replacing gasoline.

I suspect your napkin math is probably calculating a different use case which is not the most common intended use case of car batteries, but rather, if even practical at all, only a trifling convenience, the scale of which will be lost in the noise when compared to actual driving usage.

Again, what was your point?
