Parking Lot Mechanics

I'm still failing to comprehend the mechanics of the parking lot in Indonesia. Take the lot at Plaza Renon, for instance. In order to exit the lot, you must follow a road to the pay station. Now, if you have a line of cars waiting in line to go through the pay station (and it can be a considerably long line at night), and if the drivers of motorbikes keep advancing along the sides of the cars in order to get to and through the pay station more quickly, how is the line of cars to move? Or for that matter, the motorbike driver (me) who has been dutifully waiting behind the cars? By what reasoning do these drivers arrive at the conclusion that their behavior is appropriate? Perhaps it is merely because no one tells them it is not. Maybe it's that simple. In America, someone is going to tell you to that you are behaving inappropriately. Although they won't use those words. I dunno. Perhaps it is inappropriate here in Indonesia to tell another person that he is behaving inappropriately.
