The most recent discovery in Cyberpunk 2077 appears to be an abandoned monorail system in the city. If you look up into the sky, you’ll see there are a ton of raised platforms and bridges all around on pillars, but they’re not for cars. Someone on Reddit managed to climb up on one and discovered there is an entire monorail track network and stations spread throughout Night City, but they’re inaccessible. The system is called NCART, which stands for Night City Area Rapid Transit, which by logic suggests they were adding a fast-pass system to reach key points in town without needing to use a car. The video below shows a platform and a station, but they have removed the insides of the building and (most likely) disabled the entrances on the ground level so you can’t get in, let alone go up.
