Double vision (ghosting) at night through windshield?

Someone should be tweeting Elon about this issue, constantly until Tesla does something. This is not acceptable.

Keep doing it, tweet bomb him. I don't have a twitter but I do have IG but he's not on it ever. The more it's tweeted the sooner he will respond.

I am sure most of you with this issue have read this article?

The first test drive X that Portland got had ghosting really bad, during the day as well (to me anyway), the second one they got did not have it and luckily mine does not have it but from what I have seen during the day it's bad.

I had mine tested and received the standard "within specifications" response. I asked a couple times for additional details and just received this:
The American National Standards Institute is the organization that sets the tolerances for the windshield image duplication. Below is the link to the specific document along with excerpts that give the specific measurements.
The section in the document that covers this is 5.10.2.1
http://www.interautoglass.org/content/17473/download/clnt/18339_Draft_ANSI_Z26_11.pdf
As per UNECE43 and SAE Z26 standards, secondary image separation should not exceed 15 arc-minutes in Zone A and 25 arc-min in Zone B
Tesla is effectively saying their standards consider it acceptable to have the maximum allowable image separation. Another way of saying it is their standards are the absolute lowest legally permitted. It is incredibly frustrating to hear them talk about the "very best in quality, safety, and service" when clearly their tolerance on this issue is the nowhere close to the very best.

"It's totally normal because of the angle of the windshield. But try some things out like special magic glasses and moving your seat up and down, which may make it go away, despite being totally normal."
That's pulled from the NHTSA, as I posted a few weeks ago people should really report it, but nobody seems to have done it so far. Still the same 7 windshield reports....

All, has anyone found a solution?!!! The picture below is of the test being performed on my new Tesla at Service in Burbank. I picked up my Model X only a week ago and immediately noticed horrible ghosting, both at night and during the day. Tesla replaced the windshield because of the ghosting (perhaps, keep reading) and irregularities (folds) in the glass on the passenger side. The problem was not fixed. I took the X back to Service this morning and they informed me that they would test again, but if the windshield was "within California safety maximum allowable deviations" they would not replace. This time Tesla performed the test while I was watching (I didn't watch the first time so it's possible they only replaced the windshield because of the passenger side irregularities).
For the test, they placed the pictured card on a stand 5.9 meters in front of the car and turned an LED on in the center of the card. The windshield only fails if the aberration (ghosting) occurs outside the circle.
As you can see, my ghosting is obvious, but only maybe half to 3/4s the maximum allowable "badness."
This is terrible. Basically, for a +$100k car, Tesla is just accepting that the windshield is 1/2 to 3/4 bad.
Oh, and the service guy gave me the "it's the angle of the windshield" line. Then he said that the ghosting varies between Model Xs. I strongly pointed out to him that his two statements were in direct conflict as all the angles of the Model X windshields are the same.
It's pretty bad. I'm getting eye strain and headaches. Anybody have a solution?

The thing is, the problem gets much worse when the source is more distant. 5.9 meters is not that far. I think the standard they are using for this needs to be revised.
I installed a second Model X windshield, reversed, facing the roadway. I had to glue it to the hood. This inverts the image twice, canceling the ghosting out, but it also acts as a parachute and reduces my range to 12 miles.
Any easier solutions than ohmann's?? I agree with the 5.9m being short. I found that the reason for the distance is that CA safety specs define the test at 25ft from light to eye. So they measure 19ft (5.9m) to the front + 7 feet to the driver's eye inside the car. I'm not supporting or justifying through. It's really horrible.
I'm fine with the little imperfections and uneven panels. But not being able to drive without eye strain and headaches?
This is unbelievable.
