If you shoot the guy pushing him, he grabs the wheels himself and hauls ass through the door.
While fighting him, you can sneak up behind him and hold him at gunpoint, making him give up his camo. He also freaks out when you shoot his parrot
and then throw it in front of him after sneaking up behind him.
