Oh oh! And don't forget that little side map! And in Jak 2 you could get attacked by cops.
Hmm and wasn't there a part in Jak 3 where you were in a buggy with Sig, and you had to shoot those Metal-head dinosaurs with cannons? That was like a drive-by shooting(it's hard to explain you'd have to play it)... kinda-sorta.
EDIT- and playing a Jak(2 or 3) game for 5 minutes or less doesn't show the likeness of GTA, those 5 minutes are just tutorials and such.
