---------------------------------------- Can you tell the difference between regen and friction braking? If so then you should be able to tell how well the regen is working for you and adjust your driving style to maximize the regen effect. On my Honda Insight the very top of the brake peddle is regen only, so it is easy to control the regen yourself. I have yet to drive a Leaf so I do not know if there is any control left to the driver.
