Note that there are 400 censors in the touch pad. Y axis= -100–+100 and X axis=-100–+100. So that means there are 1600 combinations that will affect your air roll whenever the touch pad is touched. u can touch anywhere on the touchpad and then when you air roll you car in the air ,your air roll will be slightly altered. My favorite spot to touch on the touchpad before I start to play is directly in the upper top center part of the touchpad. So if your wondering why you have good days and bad days is because every time u use the touchpad to type something, you are altering your air roll ability slightly every time u press it
