Earlier quoted context omitted.
He's at his lowest point in the eyes of the media (which is how most of us see the world) but hes actually at the highest point in his career and achievements. Tesla is about to explode in production with their "biggest building in the world factory" in texas, berlin and china. SpaceX is about to achieve the holy grail of the space industry (an affordable and reusable rocket) not to mention Starlink.
Tesla cars are garbage, speaking as a Tesla owner. They demo nicely, but they are put together poorly. The minute there's any meaningful competition they'll crumble. Combined with the risks from their autopilot system and their mistreatment of workers and their CEO being a right wing edgelord? There's plenty of reasons to think Tesla might not be on a good path.
Other than tire rotation, cabin air filter change, and wiper fluid refill, our cars have required no maintenance.
But arguing from anecdote doesn't really help.
