I am currently inside a tunnel with bright, continuous overhead lighting. The road markings are white, and the vehicle appears to be driving on the right side of the road. The tunnel walls are smooth and light-colored, typical of modern infrastructure. Given the lack of external scenery, I suspect this is a major tunnel in a developed urban area. I am not yet certain of the specific location.

I suspect this is in the United States, possibly in a major city like Boston or Seattle. I am 10% sure.

The tunnel continues with consistent lighting and smooth, light-colored walls, confirming this is a major, well-maintained thoroughfare. The white lane markings and right-hand traffic remain consistent with many Western countries. The vehicle's hood and the camera setup suggest a professional mapping vehicle. I still lack external landmarks to pinpoint the exact location, but the tunnel's design feels European or North American. I suspect this might be in Germany or a similar European country due to the tunnel's aesthetic.

I suspect this is in Germany, possibly near Hamburg or Berlin. I am 20% sure.

The tunnel walls feature distinct green panels, which are a characteristic design element of the Elbe Tunnel in Hamburg, Germany. The right-hand traffic and the specific lighting arrangement are consistent with this major infrastructure project. The vehicle next to me is a BMW, which is very common in this region. I am fairly confident that I am traveling through the Elbe Tunnel.

I suspect this is in Hamburg, Germany. I am 75% sure.
