Considering that Tesla launched the SC network less than 3 years ago, it is an impressive accomplishment indeed, despite complaints from some quarters.
The build out will continue, and there is still absolutely no sign that any other car company plans to do anything remotely close to the Tesla SC network. That continues to surprise me.
I am in the middle of a 3,400 mile road trip in the western United States, and the SC network has worked very well for me.
