If I'm reading this correctly, this article is based on experience charging one time at one single Shell charging station?
I've charged at a few dozen Tesla superchargers a hundred times, across the US West, Central, and Eastern regions. One thing I've often wished for was more of a gas station like option, to get and leave beverages, etc... Newer Tesla stations seem to tend towards being better about this, but especially in 2017-2019 it was easy to be stuck for a 45 minute charge in the middle of a closed shopping center with nowhere to go.
The Shell setup you describe sounds like exactly the sort of Supercharger I like the most these days.
This is largely for long distance travel, FYI.
