Knowing nothing about the design of the battery swap, the building itself looks like there could be enough room for a lot of batteries (depending on how efficient the storage is). When I go to Hawthorne for SC the status screen showing the top ten or when it loops through individual locations, I don't recall ever seeing one with over 100 charges. I go late (about 10 PM) and I remember Hawthorne was at 73. I have noticed that people seem to go to charge about the same times, so it might give the appearance that a lot of people use super chargers, but when I have gone to super chargers, I have never seen more than one or two.
In the past week, I have been to Oxnard (afternoon) and Hawthorne (10PM) and I was the only one at Oxnard and only two others at Hawthorne. Based on that, it could be years before they are doing more than a hundred swaps. How will most people use them. Single day business trip? Weekend? it will be interesting.
