Elon Musk appeared visibly distressed during a Fox Business interview, discussing the difficulties in managing his multiple ventures amid Tesla's 15.4% stock drop. Investors are worried about Musk's political involvement distracting him from Tesla,

Former EV darling Tesla is being smashed by a series of massive problems as backlash against Elon Musk’s political behaviour continues to snowball. Tesla shares have plummeted today, dropping 15 per cent to its lowest price since October. The stock is now down approximately 45 per cent since its all-time high of $1.5 trillion in December.

This suggests that a reaction from consumers who dislike Mr Musk’s antics are only one reason for falling sales. An updated Model Y, Tesla’s best-selling vehicle, has just gone on sale.
