"GTA4 is a good example of fake AI, artificial intelligence that only pretends to reason. This is very common in video games, as their primary goal is not to plan realistically and beat the player, but to provide enjoyment and make (smart) mistakes. This becomes apparent in how the game handles the appearance of police units. When your wanted-level increases, there are suddenly more police cars and cops around (especially for the higher levels), that come pouring out from behind street corners or are just there when you turn around. This behaviour, while perfectly legit for a game, would be useless in real life. All the steps which are most important for navigation and reasoning in robots and "proper" AI are cropped away in video games. Therefore there is -still- no possibility that non-player villain behaviour (would that be the police then, in GTA IV?) accidentally or even on purpose crosses over into the real world from a game AI..."
