There are different regenerative brake settings. In our orientation, the dealer said not to leave the highest regeneration level on while driving because somehow that uses more energy. On other electric vehicles, it doesn't matter. In fact, you can pretty much use the accelerator as a brake simply by easing up on it. One pedal to accelerate and brake unless extra braking was needed. It seems like a pain to have to manually hit the paddle to turn on the regenerative braking EVERY TIME you want the regenerative braking to slow the car down. So I wanted to know if it was okay to just leave it on the highest regenerative setting 100% of the time.
