I'm not a driver, so keep that in mind, but it seems intuitive for me that it would be nice on the joystick to have it default to low gear and then when the trigger or a button was held, it would shift to second gear, when it is released, back to first... kind of like a turbo button.

I say this because in my opinion, low gear is for precise driving and motion and high gear is for moving quickly between two points.
