A video shows a street transformed into a go-kart track, lined with red, white, and green barriers and metal fencing for spectator safety. The track is on an urban street, with a large building on the left bearing the inscription "СОФИЯ". A tall pine tree stands in front of the building. In the distance, a Red Bull archway marks a section of the track, and spectators line the edges of the course. Several go-karts race along the track, some blue and some red. The sky is partly cloudy with blue patches. Wires cross overhead and there are light posts along the street. A traffic light is visible above the track.
