You'll probably first notice the passengers expression because of their direct gaze (eye contact being the strongest way to attract a viewer's attention). Next, your attention will likely cycle around the passengers flapping t-shirt (which has been deliberately painted in green; the complimentary colour to red, which is used for the vehicle) to the passengers arm, which leads you past the driver, down to the cartoon character, and on to the twisting tubes and detailed engine, before coming back up again to the passenger.
