Man, that face palm meme would be useful in answering your post as well.
I know, right?
You would be factually wrong based on every NDA I've ever read and signed, and I've read and signed a lot of them over the years due to the nature of the work that I perform from time to time. I don't have the exact verbiage of the Tesla factory tour NDA but when I go on mine next week I'll be sure to read it and correct anything that I've mistyped based on what's in the actual agreement. However, I have never seen an NDA that allows you to disclose what you see simply because the public knew it was there...

Still waiting for jeffro01 to correct everything that he mistyped.
