You are being generous Tesla claims they get 10% back and proud of it. I much prefer the coasting to regen. I wish I could turn it off

I can't let this statement go unremarked as it propagates a common misconception. Regen captures some of the power lost from braking or going downhill, but the efficiency is probably 15-25% of the total energy used to accelerate or climb the hill initially. So it re-captures "much" more than an ICE vehicle does using mechanical brakes that drop the energy as heat, but it is not a magic energy recovery system. (Unless you have your vehicle towed to the top of a hill, all of the energy re-gen captures came out of your vehicle on the way up the hill or acceleration curve.) Coasting without power is MUCH more efficient than stopping with regen and then re-accelerating in a BEV (or an ICE for that matter).
