Netherlands train doors

I probably wouldn't say this unless I actually saw it happen at least three times. On several occasions I have personally witnessed people who try to catch a Dutch train with about 20 seconds to go before the doors will close and they try to see if they can get into the doors in the farthest train car. For example the stairs leading up to the train in question has the door open and the whistle has blown meaning that the doors will soon close. Someone runs up the stairs and tries to run to the doors of the train about 100 meters away. Obviously they are training for the Olympics. Why not just enter the train at the closest point, then walk down the train to the point where you want to sit? Another thing that bothers me are people who walk up and down the train for about 15 minutes trying to find that one "perfect" place to sit. Once they find the perfect spot they sit for less than 5 minutes because their train is about to make a stop where they wish to depart.
