-The taxi driver will play a significant roll into the gameplay. If Niko wants to go to point B, from point A, on the map, he can take the ride with just a push of the Y or Triangle button. This time around though, the taxi-driver will fulfill some special wishes. If Niko is hungry, the Yellow Cab will drive him to the next Food restaurant.

-Committing crimes isn't as easy in GTA IV as other previous games were. You gain a wanted level for every crime you commit, as long as there are witnesses present.
-Once you have gained a wanted level, a visible (circular) search area appears on the radar, and if you escape this area without being spotted, your wanted level will flash and disappear. If you are spotted, however, the search area's position changes, and centers on where you were last spotted. So unlike previous GTA games, the police don't always know where you are. They can't catch you unless they find you first. It was confirmed previously that in GTA IV every street will be named, and this is what cops use to communicate when they are tracking you down.
-There are no Pay N' Spray's to save you this time, unfortunately.
-Once you gain a wanted-level, the map flashes with circles of blue and red, with each circle representing the line of sight of the police chase. The circles differ in size depending on your wanted-level.
-There are 6 levels to the wanted level.
-Cops now can crouch to improve their accuracy for the long-range shot at you.
-The Police will appear on the map as 'dots', while they are on search for you.
