I am flying through a tunnel with traffic moving on the left side of the road. The lane markings are white, and the tunnel architecture looks modern and well-maintained. The green arrow lights above the lanes are characteristic of traffic management systems often found in tunnels in the United Kingdom or Hong Kong. Given the style of the tunnel and the vehicle types, I suspect this is in the United Kingdom, likely near London. I am moderately sure about this location.

then: forward

The vehicle in front is a Toyota Alphard or Vellfire, which is very common in East Asia. The tunnel walls and lighting design are characteristic of major infrastructure in Japan. Driving is on the left, which matches Japanese traffic laws. I am confident this is in Japan, likely in a major city like Tokyo or Osaka.
