Yes, I agree, most of this could have been scripted. But then agian, when you start getting into so many advanced scripts going at once... it's insane. Let me give an example.
Car1 - Grenade blows up
Bus1 - Grenade blows up, and lands on it's side
Car2 - Passive driver, gets windsheild cracked from explosive blast. Gets out of car.
Car2 driver - checks script options for passive person. Run safest way across the road to the sidewalk, and then hide in nearest ally.
Car3 - Psycho driver, gets hit by flying pedistrain. Mashes on the gas, swerves into sidewalk and drives down sidewalk.
sidewalk people getting run over by psycho driver in car3 - Depending on personality, they stand there (grandma) run behind the brick stairs leading to their door or go hide in the closer phone booth, but no real saftey?(passive) Agressive drug dealers would pull their gun out and start shooting at him.
Drug dealers down the road hear their buddy shooting, come running to protect their buddy.
EDIT: I dont feel like going on, but this isnt even half the AI objects.
All AI is basically scripted. It depends on how many scripts and how much they can do, and how many objects are being effected by the AI. I doubt the AI on GTA4 would work on a x-box.
