For cars with frameless door windows, it allows the glass to slot into a channel so it doesn't bow out at speed. Also increases anti-theft security because you can no longer just peel the window out enough to reach in and unlock the door.
If they're doing this to FRAMED windows, that's indeed stupid. But it has a purpose on frameless windows.
What usually fails are the microswitches in the door handle, BTW.
