A media relations department is a savvy thing to have in order to keep your brand’s reputation healthy. An order backlog stretching into 2023 doesn’t mean much for the next decade of Tesla. Public opinion is important for sales. I’m not going to claim to speak for the car-buying masses, but my impression of Tesla (false marketing claims, shoddy workmanship, bad working conditions, etc) is bad - you’d think a competently run company would want to try to shift that narrative.
