I don't know about other places, but did my first longer trip and used a few superchargers. Tejon, Harris, and Gilroy. All 3 had over 50% spaces filled and two of them were 100% or more filled at some point I was charging. Did get to see a P85D, but also noticed that most of the people there charging had no understanding. One person couldn't disconnect the cable, because his car was locked. No one I spoke to understood that the chargers were paired. It's only going to get worse... At Harris, someone had to wait for a spot to open up. Unfortunately, there were at least 3 cars that were there before I got there and after I left. The one good news was that none of the spots were iced. Just some observations.
