The American company Embark has taught an unmanned truck to present documents to the police.

The truck detects that a car with a flashing light is following it - with a high probability this means that the police want to stop it. The drone sends a signal to a remote operator: he watches the broadcast from the cameras and decides whether to stop. After parking, the police officer can request the documents of the car, which are stored in the safe. To do this, you need to call the operator at the number written on the back of the truck and request a code. After checking the documents, the policeman can clarify the details with the operator and put the papers back in the safe. After that, the truck will return to autonomous mode and continue driving.
