During the first-quarter call in May, Musk cut off Toni Sacconaghi, senior technology analyst at Sanford C. Bernstein, dubbing his question on Model 3 gross margins "boring." He took a first question from Sacconaghi on Wednesday, and promptly apologized for his prior conduct.

On July 16, Tesla stock plunged again after Elon Musk insulted Vernon Unsworth, a British cave diver who helped rescue 12 Thai boys and their soccer coach, on Twitter. Unsworth said he was considering legal action against Musk, because the CEO labeled him "pedo guy."
