Your windows are superior in how they open, however the average American would need better education in order to operate them.

I was just there in June and my apartment had 3 options for the window to open depending on latch position. One would open the top for venting, one would open wider with just the glass part of the window leaving the bug screen in place and another would open the whole unit so you could hang out the window and fall 10m to the ground.

Best we have what are called double hung windows, top and bottom open (up/down or left/right side slide). Almost every house i’ve ever lived in has screens.
