This whole incident sort of blows my mind. It seems like this should be Operating a Public Company 101 level knowledge, and the fact that he failed so spectacularly leads me to believe either someone at Tesla or the exchanges screwed up royally with the timing of some preliminary work and Musk didn't make sure it was done ahead of time, or he was drugged out of his mind on Sudafed or something (either because he thought it was okay or thought he could get away with it). I'm honestly not sure what's more likely given how stupidly obvious the error is.
