His explosive row with US President Donald Trump - and the very public airing of his dirty White House laundry - suggests Musk's changing priorities might not quite be the salve they had been hoping for.

Instead of Musk retreating somewhat from the public eye and focusing on boosting the fortunes of Tesla and his other enterprises, he now finds himself being threatened with a boycott from one of his main customers - Trump's federal government.

Tesla shares were sent into freefall on Thursday - falling 14% - as he sounded off about Trump on social media.

They rebounded a little on Friday following some indications tempers were cooling.
