Can you explain what the word "regenerative" means in the context of an ICE vehicle decelerating? Your description above doesn't indicate that anything is being generated. You indicate that the generative impact seems trivial, but this is not the case for me. In my PHEV, I get an additional mile of range when I brake regeneratively getting off the freeway. This is non-trivial in a vehicle that only offers about 12 miles of EV range. It's one of the reasons that my average MPG hovers between 90 and 100.
