Honestly the title doesn't do it justice, it's more a general vehicle spawner since you can set stations and car sets to be anything. It's great for every type of ambient scene that doesn't require peds you want to permanently set up, like a construction site, a sports car impounded by the police etc.
Amazing mod, congrats, it finally allowed me to spawn the LSSD at the Davis Station, the ULSA Police at the campus and the park rangers at their stations
If you have stop the ped then your rifle and shotgun are in your trunk, press G and grab them from the contextual menu. If you want all your weapons on you you can disable the script also in the G contextual menu
