NMS would be great, but I do not think it will happen. The questionable implementation of the most hated systems (police, city AI, traffic) seems to be the result od some technical problems with the engine, streaming data and storing them all at once in memory.
That's why the engine is unable to keep track of AI once out of sight (not to be confused with standard rendering techniques) and simulate some random interactions between NPCs (drivers, pedestrians, police etc.). That's why many car sprites spawn and despawn in the distance, random AIs materialize out of thin air in back-alley portals, follow scripted paths, then dematerialize (if the player turns his/her head around) not to be seen ever again in the exact same form (and I do no mean the model or outfit only). That's why CDPR decided to implement these severely outdated systems that would be considered merely as placeholders by some other AAA developers.
Solving RED engine problems would probably require many, many additional working hours, some massive redesign of the game and quite long testing (QA) process. I doubt if it is possible considering well-known problems with the last-gen consoles. So... do not expect it to be done any time soon. Frankly speaking, I do not think that they will ever address these issues.
I hope I am wrong.
