It is pretty easy. I find if the owner is not right there, putting your greasy hands on the car and sitting in it with your cup of coffee finds them pretty quickly.
A "problem" is not a picture of cars blocking a supercharger. A "problem" is when you want to charge and a stall is not available. I did not see a Tesla in the photo.
We can be the "victim" and call "the man" whenever someone inappropriately infringes on an EV parking space, or we can be part of the community, have a "conversation" (that is the woke term, right?), and see if we can work things out.
I've seen superchargers completely blocked due to parades and other events. 2 hours for a bunch of people occasionally meeting on a Sunday morning to enjoy their cars is not that big a deal.
Our CT Tesla group meets every month at a Starbucks, using their parking spaces. Starbucks has not harrassed us - even when people show up with their Dunkin Donuts coffee cup!
