I am currently flying through a long, modern tunnel. The road markings are white dashed lines, which are common in many countries, but the tunnel's architecture and lighting style feel very distinctive. The tunnel appears well-maintained and clean, typical of major urban infrastructure. I suspect this might be in a developed nation with significant tunnel networks. I need to see the exit to identify the surroundings.

I suspect this is in Australia, possibly Sydney. I am 20% sure.

then: forward

The driving side is on the left, which strongly points to Australia. The unique arched structure over the motorway is a very specific landmark, and the skyline in the distance looks like Sydney's central business district. The vegetation and the bright, clear sky are consistent with the climate of New South Wales. I am now quite certain this is the Western Distributor or a similar major arterial road in Sydney.

I suspect this is Sydney, Australia. I am 85% sure.
