Got it, and likewise I could have not made assumptions and jumped to the conclusion that I understood your comment. I got lost between theory and practice. I think I agree with all of what you said when we're talking about theoretical limits and theoretical near 100% efficient regeneration. It's just that in practice, regenerative braking on a Tesla is not that efficient, and it isn't something that recovers most of your energy spent accelerating, it only recovers a minority share normally, and often only a very small minority.
