I am currently inside a tunnel with distinctive orange-yellow wall paneling and bright overhead lighting. The traffic is driving on the right side of the road, which is common in many European countries. The road markings and the style of the tunnel suggest a modern, well-maintained infrastructure typical of Germany or a neighboring country. The presence of a bicycle on the camera vehicle is quite unusual for a tunnel, suggesting this might be a special mapping project or a cycle-friendly urban area. I suspect this is the Elbtunnel in Hamburg, Germany.

I am 70% sure of this location.
