> It seems to me like you could easily implement regenerative braking in the same way by having the brake pedal respond to light pressure with regenerative braking, and firm pressure with brake pads. It already works exactly like this. It's called "blended braking". One pedal driving is a different feature. It's intended to get even more regen, by encouraging more gradual deceleration. If your habit is to already avoid hard braking, then it doesn't really increase efficiency because you'll get the same benefit from the brake pedal.
