Product placement
(a) JINLIN hand control device: it ACTS as the interface operated by the user to control the vehicle's pedals. Removing it would change the video entirely as it is the subject of the demonstration. (b) BYD Sea Lion 05: it merely APPEARS as the vehicle being modified. Removing it would not change the functional demonstration of the hand control device.
