A Tesla semi truck is making its way across country alone without escorts or backup chargers. This is welcome news for the company, which has been receiving blows lately, especially for its ill-starred production of the Model 3 sedan. Elon Musk has been on the edge of losing control. He has been doing too much for too long, starting companies and attempting to run them while perfecting a highly complex manufacturing process. Bad news has come in spates, and he is in debt in the billions. Tesla is upright but it is on the thinnest of ice. Any more bad news and it can plunge into bankruptcy. Musk is well aware of his position, and he is in dire want of good news. The journey of the semi might be what he needs to fight another day.
