And this points out one of the failings of the team. It almost seems as like they were "taking the easy win" and putting sites in where it was easy to get them, where they really need to work hard on filling actual gaps. (And adding capacity where necessary, especially in V2 islands.)
Hey, isn't that exactly what Elon says that they will start doing now, as the team is reset and rebuilt?
In addition, Elon likely had more insight to recent downtime stats which maybe weren't ideal. (Anecdotally, I have seen a lot more reports of problems at Supercharger sites lately than I had seen in the past.) Though reliability is likely mostly a result of the maintenance team, which, from what I have seen, wasn't let go.
