I am inside a tunnel with white tiled walls and orange lighting. The road markings are dashed white lines, which are common in many European countries. The tunnel appears well-maintained and modern. Without external landmarks, it is difficult to pinpoint a specific location, but the aesthetic is very typical of tunnels in Northern or Western Europe. I suspect this might be in Germany or a neighboring country.

I am not very sure about this location.

The tunnel remains dark and uniform, offering very few distinct environmental clues. The lighting and tiling style are consistent with major infrastructure projects often found in large European metropolitan areas. The road markings are standard, providing no specific regional indicators. I am still essentially flying blind in a subterranean environment. I will guess a major European city known for extensive tunnel networks.
