How to become a star of Google Street View

This video was shot in Berlin. A group of German teenagers follow the streets of Google Street View, taking pictures of streets. Although the car with a tripod on the roof and the logos on the sides is already noticeable, they say that the brave guys managed to attach a GPS transmitter to it so as not to lose sight of it.
At first, the teenagers simply waved their hands and shouted (the driver, apparently, did not even hear), then they started throwing faki towards the camera, making faces, and at the end three guys even took off their pants.

They say it is not just hooligans, but participants in the Free Art and Technology movement.
