With normal "braking", the mechanical brakes don't engage. If you drive like you own a hybrid, the mechanical brakes will only engage in the last few feet of a full stop. Regen braking at speed can be amazing. Often coming to a stop, I will lower my set speed on cruise control by 30 mph, pretty brisk slowing (same effect as the brake pedal). Of course, I try to slow down earlier, but don't like to annoy traffic behind. I use the "hand throttle" (cruise control) for 90% of all driving above 20 mph.
