You really only have 1 axis of control with a brake pedal because you have to take your foot of the gas first. With one pedal driving at least you don't have to take off your foot. One pedal driving for me only makes sense if you keep a proper distance to the people around you, such that the limited braking force is sufficient to flow with the traffic, so that wouldn't apply to many drivers out there. Perhaps that's where the confusion comes from.
