Yeah, those empty tunnels feel like a living corpse of the city. The dust, the graffiti, the echoes all give a frame that says “here’s a story waiting to be told.” If you want to map that scientifically, you’d start with light levels, acoustic decay, and human movement patterns. In practice that means putting sensors in the tunnel, recording how sound travels, and watching how people drift through it. Then you can overlay that data onto a film set and see if the audience’s attention follows the same invisible paths. It’s basically turning city grit into measurable storytelling.
