Why auto makers dropped the frameless doors?
Because they really didn't work too well. It was too hard to build a seal between the car frame and the glass, that worked well when closing the door, while allowing the window to slide up and down. Because you couldn't hold the glass in a channel, the window gets pulled away from the seal at hig…
The Short Answer
Because they really didn't work too well. It was too hard to build a seal between the car frame and the glass, that worked well when closing the door, while allowing the window to slide up and down. Because you couldn't hold the glass in a channel, the window gets pulled away from the seal at high speed, unless you design it to push tightly against the seal, which makes the door hard to close and makes the window-winder mechanism stiff. The door-window seal has to do different things to the door-car seal. Trying to make one seal do both meant that both things were done poorly.
