I am flying through a tunnel with distinct yellow and black wall markings and white chevron road markings on the left. The vehicle is driving on the right side of the road. The tunnel architecture and lighting style are very characteristic of modern European infrastructure. I suspect this is a tunnel in a major city in Italy, possibly Rome or Milan, given the specific aesthetic of the tunnel walls. I am moderately sure of this location.

The text on the tunnel wall clearly says "Hallepoorttunnel" and "Tunnel porte de Hal." This confirms the location is in Brussels, Belgium, as the city is bilingual (Dutch/French). The tunnel is a well-known part of the Brussels inner ring road. I am very sure of this location.
