I am flying through a long, modern tunnel with smooth, light-colored walls and linear lighting. The vehicle on the right appears to be driving on the left side of the road, which is common in places like Australia, the UK, or Japan. The tunnel's architecture looks very clean and well-maintained, typical of major urban infrastructure projects. Given the specific look of the tunnel walls and the lighting, I suspect this is in Australia. I am moderately sure this is in Sydney.

then: forward

The tunnel environment remains consistent, with clear lane markings and a modern design. The vehicle in front is driving on the left, which confirms my initial assessment of a left-hand traffic country. The specific lighting and wall panels strongly resemble the NorthConnex or a similar major tunnel project in Sydney, Australia. I am fairly confident this is part of the motorway network in Sydney.
