I am in a tunnel with distinct orange walls and bright, linear lighting, which is characteristic of many tunnels in Germany. The vehicles are driving on the right side of the road, and the road markings are white dashed lines typical of European highways. The presence of a bicycle in the tunnel is unusual but suggests a specific urban infrastructure. The overall design and lighting style strongly point toward a major German city tunnel. I suspect this is in Hamburg, Germany, likely the Elbtunnel.

I am 60% sure.

The orange tiled walls and the specific lighting configuration are iconic of the Elbtunnel in Hamburg. The presence of a bicycle on the back of the vehicle is a common sight in Germany, where cycling infrastructure is highly integrated. The road markings and the general tunnel architecture confirm the German location. I am very confident that this is the A7 Elbtunnel in Hamburg.

I am 95% sure.
