Where Does GTA 4's Garbage Go?

Thousands of bags of garbage are left in GTA 4 every day, what happens to it? Does it get collected? Or is this all one big illusion? I spent days in GTA 4 following missions and watching trash collection trucks in liberty city. I followed the garbage collectors NPCs around, trying to answer the question, Where does the garbage in GTA 4 go? GTA IV is still celebrated as one of Rockstar Games most realistic open-world games. Its cars have weight, its pedestrians react dynamically, its restaurants are enterable, and Liberty City feels like a place that exists beyond the player. But how much of that city is truly being simulated? #gta4 #libertycity #gta
