. Upon validation of its participation in the STS
protocol, the vehicle in front starts a geo-unicast video
streaming to the ZOR of the overtaking vehicle of the signal
collected by its windshield-installed camera. The overtaking
vehicle receives this video streaming and displays it to the
driver through the dashboard screen. The overtaking vehicle
sends a message to end the protocol when the overtaking
is completed, which is automatically detected by its GPS
position and the ZOR of the video-streaming.
