I am flying through a tunnel with distinct yellow wall paneling and a specific lighting arrangement. The vehicles are driving on the right side of the road. The blue car ahead has a European-style license plate, and the tunnel infrastructure looks very modern and well-maintained, typical of Northern or Western Europe. I suspect this is in a major city in Scandinavia or Germany. I am 20% sure of this location.

then: forward

The tunnel design with its distinct yellow wall paneling and specific lighting is highly characteristic of the Södra Länken tunnel system in Stockholm, Sweden. The blue car and the overall tunnel infrastructure align perfectly with the standard look of major Swedish road tunnels. The signage and emergency exit markers are consistent with Swedish road safety standards. I am 85% sure this is in Stockholm, Sweden.
