TLDR:

The NCPD doesn't care for a few citizens' death, so it's only natural they don't send reinforcement to the scene for "minor" crimes. NCPD and MaxTac now react differently based on how much eddie they're getting from the district. This stopped them, or slowed them from showing up in a specific district.

NCPD & MaxTac New Behaviors:

In general, Night City is a hotbed of "crime" and NCPD has started to strive for Return on investment (RoI) after privatization in 2076, they just couldn't care for a few hit-and-runs or deaths due to "weapon malfunctions." Though when it is no longer a minor crime, the NCPD will head to the scene based on the district status! (Those poor dudes can't even afford to call the 911 anyway, haha.) Anyhow, the Night City Council has divided the Night City into 6 major districts and 16 sub-districts plus the Badlands outside of its jurisdiction, and this more or less is how the NCPD decides on their actual response.

City Center  ---------  Corpo Plaza and Downtown
Watson  --------------  Northside, Little China, Arasaka Waterfront, and Kabuki 
Westbrook  -----------  North Oaks, Japan Town, and Charter Hill
Heywood  -------------  Wellsprings, The Glen, and Vista Del Rey
Santo Domingo  -------  Arroyo and Rancho Coronado
Pacifica  ------------  West Wind Estate and DogTown
Badlands  ------------  Badlands


Each of these sub-districts has their own socioeconomic status:

North Oaks has some of the wealthiest residents throughout Night City; Japan town and Charter Hills are home of those who make banks; and City Center is the heart of Night City. These districts, among a few others, have the tightest security to secure the eddie flow from the City to the Corpo. The City does not hesitate to hire MaxTac to eliminate any threats!

Yet, once we exit these wealthy sub-districts, like if we leave Corpo Plaza to Vista Del Rev, and eventually enter Arroyo, we can easily notice the economy of our view deteriorates quickly. NCPD doesn't want to handle crimes in these areas unless it gets ugly. If you see NCPD officers around these districts, they are probably up to their own corrupted businesses for some extra eddies. Of course, since these poor and inconsequential sub-district are still unfortunately a part of the Night City, the mayor (deceased) has to put our valuable funding from the City Council to hire MaxTac for potential cyberpsychosis to lower the crime rate and to win the next election!

Pacifica is now declared as an "independent district" of Night City, so -- just like the Badlands -- there is just no one to step in for any homicide or mass shootings. The City council isn't counting the deaths there for the official life expectancy statistics anyway!


* Districts were generally divided into four categories: the Lawless, the Poor, the Normal, and the Rich.

By default, this is how the City look like in the eyes of the NCPD and MaxTac


Configuration:

Since Mod Settings is now up, you can go the the Setting menu down the Game menu and change the settings. You can set your status for each district, NCPD spawn detail coming on foot or on vehicles, and MaxTac spawning requirement. (I set up two config for number of AV or the minimum number of MaxTac left before respawn based on how the vanilla code was written, but -- seriously -- I can't even manage to kill any of them let alone testing their behaviors...)

Installation:
Just drag the file to the Cyberpunk game folder (*make sure you see the folder r6 before dropping)

Uninstallation:
Simply remove the mod and restart the game.

PSA: There was a bug on base game. It seems it is possible to have no NCPD reaction after removing the mod, yet temporarily fixable by waiting for 24 in-game hours. I cannot seem to recreate the bug to confirm.

Compatibility:
Check the overlapped functions in mods yourself, or ask if you wanna know (may answer when I'm free.)

My mods:

• Autosave Disabler Plus - Disable autosave during various in-game events
• Weapon Conditioning - It introduces condition stats to all weapons and penalty mechanisms due to poor conditions. Believe it or not, I built this to fix the economy system
• Ripperdoc Service Charge - Ripperdoc always gets paid. Also a mod to fix the economy system
• Skillful - It tweaks the pacing of character progression system on skill proficiency, character leveling, perk (point) development, and Cyberware capacity
• Skillful Attributes -  It tweaks the attribute leveling system such that attribute level is only granted through skill proficiency development
• NCPD and MaxTac Spawn Tweak - It tweaks NCPD spawning parameters with district base settings (compatible with all mods that tweak only the NCPD record)
• No Shooting Delay - It removes NPC's hardcoded range weapon firing delay
