A policeman found an invisible Audi car. What movie is it?

Driver. According to the driver's video, a policeman found that an invisible Audi car was a driver's movie. Audi A4 B5, the so-called "invisible chariot", is used by the police to enforce the law on the expressway and investigate and deal with illegal acts that seriously affect road safety, such as speeding and racing. The reason why these "chariots" are "invisible" is that these police cars are just like plainclothes policemen, and there are no police car signs on them.
