I've owned several different vehicles over the years and have never understood why sunroofs were designed to open. I do occasionally enjoy the extra light from them, but have never felt the need for them to open. All of the associated hardware, electronics, motors and gaskets necessary to open and close, for me are wasted. They also create failure points. Most likely, never opening one that opens might also cause future problems. For me, I can either pass or wish they were just like a front windshield and couldn't open.
