Yes, just got back from my service visit.
I checked out 3 cars, 1 in the studio, and 2 test drive cars. Studio and 1 test drive car were pre-production. The other car is much newer.
All 3 cars showed the exact same windshield reflection issue. This is a fleet wide issue.
It's very easy to quickly check if a car has this problem (even during the day) if you look at the reflection of the stitch line going across the dash. You'll see a double reflection on a faulty windshield in the 4-6inch region below the tint line.
I don't know how to get engineering or design involved but I really want to. My service tech suggests possibly tinting the windshield ever so slightly to see if that cuts out the effect but I really want Lucid to look for a more permanent fix (especially since they use AGP for glass, and Model X had exactly this issue)
Not sure what the next steps are but the tech finally saw the issue. I suspect Lucid is going to say it's not a big deal and to just deal with it. If only they could see it at night...
