Do you like it? I guess it brings realism into the game... but I don't honestly really like it. Now, before everyone here comes all "F*CK YOU GTA HATER"... I don't dislike the game, just this thing.
Those of you who have no idea what I am talking about:
Basically your car/motorbike can shut down and essentially become a really heavy paperweight if you stay even in low water for some time. I don't know if this was in GTA IV, don't remember having it ever happen there.
