Subway Tunnel Ride
Locked forward motion — slight mouse-driven look-around.
A first-person camera is dollied through a recycled loop of cylindrical tunnel segments while additive-blended streak meshes rush past to sell speed; segments and rails are procedurally generated once and repositioned behind the camera to fake infinite length.

Forward speed: 9.5 units/s
Speed streaks: 24, 24-44 units/s
