Nit picking here. But 50% is not quite "mostly". And "recovered" is one thing, but storing it chemically in a battery is another, and then converting that chemistry back to electricity is another, and converting that electricity back to mechanical is another, and then transferring that mechanical back to the tires, and then back to the road is yet another. Putting some estimates on those might be the original 50% multiplied by 90% * 90% * 95% *95% and we end up with only 36%. Notice I used 90% into the battery and 90% out to give a net 81% battery efficiency (to match the 80% claimed by some EV's). Others are just guesses. Though the debate will rage for a week is my guess...
