Note: Some of the above keyboard actions (such as Steering Left or Steering Right) may be overridden by additional controllers (joystick, gamepad, wheel etc.) and may no longer function.
If you select a game controller other than keyboard, you are automatically switched to the controller's settings. You should setup the controlling device properly right away, otherwise it will not work in the game. You can switch between the controller and key settings any time by pressing the button in the lower left corner of the controls settings screen. Caution, certain keyboard controls (especially related to steering) may become disabled as they may be overridden by the additional controller.
