I was initially reluctant to buy the roof gasket, but after taking a short road trip where I was the passenger, I got to experience what my wife was complaining about (a wind noise near the upper area of the passenger door glass by the A-pillar, or roof ), but it was an annoyance if riding for more than 30 minutes or so. So based on the recommendation of a few local MY owners I bought the rubber gasket from AO (less than $20 shipped) and installed it. It was a tight fit along the seem between the windshield and leading edge of the glass roof and for about 12" or so towards the rear of the roof, so I used one of these screen rollers I had on hand and got it seated flush into the channel the rest of it is loose. But after a test drive with me as the passenger and the same highway speeds (up to 75 mph) I can tell you it eliminated almost ALL OF that wind noise we heard prior to its installation.
So far it works as advertised and I have a quieter cabin. FYI we are 68+ so our hearing can be problematic, but the frequency and level of that noise bothered both of us. No longer.
But I do wish Tesla did a better job with the door gaskets.
