The whole reason this exists is because of the brush formation. The brushes in the window and seat motors are symmetrical in both directions which means they will go the same speed forward and back. However, in things such as the drill motors and fisher price motors, the brushes are aligned to be more efficient in one direction. I'm not sure why they do this, whether it increases power or not or it's just cheaper, this is the way they are designed. So it's not something that can be worked around.
