In many racing games on phones, control is carried out by tilting the body, but what if you control not the device itself, but a real steering wheel? Racing on a motorcycle is most suitable for the idea, because when driving a real bike, the steering wheel tilts the device slightly, which is as realistic as possible. If you do not know the device of the steering column of the motorcycle and the controls, then this can be seen in the pictures or video.
Cardboard steering wheel is the simplest embodiment of the idea of a gaming machine from the phone, you need to turn on the game and install the device in place of the instrument panel.
