The overlapping scenes of the two cars in the Flying Life film were created using special effects techniques. During the filming, the actors only simulated the action of driving in the driver's seat, and the car was not actually moving. Through post-production special effects, two cars were superimposed on top of each other in a computer to create this thrilling scene.
This technique is a common tool in the field of film special effects, which can make the audience feel more realistic about the scene in the film.
