Do we have a consensus on what the hold up could be?
Also, why is he posting these videos if it's not informative?
(This is regarding @elonmusk's Instagram post.)
I think he may not have had stock price on his mind as primary. I know sometimes he posts things to fix stock price related FUD, but that's not all he posts; usually he posts non-SP primary topics. But here are my two guess on both sides of that fence:
My best stock price related guess so far is prophylactic against more FUD. He might even have been tipped off that a (false) article was about to be published that such a video would absolutely refute. Or more likely, he surmised that it could just bulldoze through a few more FUD articles in a prophylactic way.
Or, he was walking out of the factory one day and said "this is cool" and posted it as cool. I find this most likely, i.e., he wasn't paying direct attention to stock price. Or maybe some Halloween scary factor that machines are scary.
I sit here thinking about it, and I realize the most most likely thing is a third thing: he's communicating to reservation holders that they're busy making some Model 3's.
I retract that third thought back to the second thought, that it was just cool.
I came up with a fourth thing. His unconscious, knowing above items #1-3, just decided this was the prophylactic responsible cool communicating thing to do, so his conscious did it. His brain probably already works at this level for at least many things, as any experienced people in their positions already do. This is car type #4 for his brain, and vehicle type #7 for his brain (including SpaceX), which doesn't even count the car type #5 and #6 already being worked on, and #7 in the pipeline someplace, and rocket type #4 (BFR) that's all the rage in his brain right now.
