Elon Musk has been described as ingenious, unorthodox and eccentric. The bold things he has done in life have propelled him and his companies to where they are today. But are his antics now hurting his most prized accomplishment, Tesla?

Tesla shares are down more than 30% this year and the company just had a very disappointing quarter. Deliveries are down more than 8% year over year, the first quarterly decline in nearly four years. It’s also down 20% from the previous quarter.

Tesla even briefly lost its title as the world’s biggest EV maker to China’s BYD but reclaimed the position this week after BYD also announced disappointing numbers.
