easiest way is to park the car about 3 feet away from the red wall, driver door facing it, if you press y the door should barely hit the red wall and it wont work, good, but you are lined up right, get back in and and press the Y button twice quickly - this will make him get out very quick and he will jump past the red wall, you are to close if he keeps getting out of the passenger door. if you stand on the AK you get get 500 bullets for it, pretty fun. other wise most of the land you will fall right thru exept for the portions outlying the demo are.
