What is the reason behind the rear windows only rolling half-way down?

Is there an easy fix to this or something I just have to live with?

the windows only go halfway down, because of 2 reasons. The Door design wont allow for the window to retract the entire way into the door, and also of safety reasons, for when children are in the back they cant climb out the open window

I remember perhaps a year ago another member wanted to change this. He found it can't be done, there simply isn't room inside the door for the windows to drop in to

Oh well, I will probably never ride in back anyways!
