I am flying through a tunnel with a very specific, modern design and bright lighting. The road markings are white, and traffic appears to be driving on the right side. The tunnel walls have a distinctive corrugated metal cladding, which is common in European infrastructure. The overall aesthetic and the presence of a bicycle on the camera rig suggest a Central European city, likely in Germany or Switzerland. I suspect this is in Zurich, Switzerland. I am moderately sure.

then: forward

The tunnel exit shows a bright, daylight opening, confirming right-hand traffic. The green emergency exit sign is standard for European tunnels. The graffiti on the walls and the specific tunnel architecture are very characteristic of the Schöneberg or Tiergarten tunnels in Berlin, Germany. The clean, modern look of the tunnel infrastructure strongly points towards a major German city. I am quite confident this is in Berlin.
