It appears to be held on with structural adhesive — Not suction fit or screwed on. I wouldn’t worry about it falling off. This is old technology. I remember in the past, many cars had the rear view mirror mounts fastened to the windshields.
I agree with the mention of the Model X visors being not wide enough, having experienced it first hand. I asked the service tech that stopped by my home this week about the visor as well because aesthetically I too would have preferred them to be on the A pillar. He claimed that that is indeed where Lucid wanted them but that new regulations required them to be on the front windshield and that it took a lot of back and worth between Lucid and the regulatory dept (whoever that specifically is) before they decided to do it in the current way. . I can't confirm or deny the truth of the statement but that is what I was told.
Is that a patented design that possibly no one else else allowed to copy?
I have had 2 Model Xs (still have one). The sun visors do really stow away nicely. The main problem I have with them is actually their ability to block the sun on the side window. When swung to the side, they don't sit horizontal (i.e they are at an angle) and pulling on them to stay horizontal only causes them to go back to an angled position. Then there is the problem that they do not extend rearward and cannot block about 4" of window by the B-pillar, which is about my seating position. For blocking the sun on the windshield, they do a much better job and since they articulate all over the place, I always manage to find a way to block the sun. I also like the magnetic holder for them. Tesla is using magnetic holders for their other cars too now and it's much nicer than clipping the visor in place.
