Elon Musk has added another bit of weird behaviour to the list by smoking a joint during a live interview.
Discussing the number of lawsuits and investigations brought against Tesla for auto malfunctions, Musk claimed that most of the lawsuits were frivolous and that people would have died if they had similar accidents in other makes of vehicle: "The S, X, and 3 have the lowest probability of injury of any cars ever tested by the USA government", said Musk.

Musk's behaviour has raised concerns about his leadership and several Wall Street analysts have called for the company to appoint a strong deputy to prop up Tesla's operations and standing with investors. "I don't actually notice any effect.I don't find that it is very good for productivity".
During the interview, the pair discussed Musk's ability to dream up ideas and inventions, with the billionaire comparing the way his brain works to a "mutation", saying when he was a child he thought he was "insane".
