Tesla is becoming a victim of their own success. 330K+ Model Ys and 3s sold in the US last year and not enough service centers and superchargers.
As both a Tesla Model Y owner and a TSLA investor, service is my single largest concern about the future of the company. They have not done a great job of scaling service along with the rest of the company, and unfortunately I don't see an effort to improve it much at the moment either. Hopefully that changes real fast.
