I get what you are saying, and do appreciate the sentiment. Most of us do police ourselves, and do so well. I doubt the abusers we all complain about are reading or commenting on this magnificent forum.
While what we are talking about is more on point with SJC and the topic of supercharger abuse in general, I will respond here for lack of an immediate better place. I feel there is a distinct difference between seeing data points on a graph somewhere, maybe buried deep in the bowels of Tesla's algorithms, compared to actual complaints heard directly from concerned customers. I have, for too long, worked in an industry where we have learned that lives could be saved only if someone spoke up, even if about a seemingly minuscule problem, one that everyone thought somebody else knew about. Given, this issue cannot compare to a life and death scenario.
There is absolutely nothing wrong with speaking up when you see something that is not quite kosher. If I was to witness someone clearly (and I do mean clearly) abusing the Supercharger process, I would think it reasonable to notify Tesla. While they may already have the data, we do not know if they have taken the time to correctly interpret it. Maybe they did, maybe they did not. Maybe they could actually benefit from someone saying "Hey, did you see that?" Tesla could then decide on whether our input was or was not beneficial. They could chose to say "Thank you. We will look into it" and move on, or they could alternatively say, "Hey, that guy is right! This customer is routinely hoarding a space for hours at a time. How did we miss that!" None of us know for sure, and given what many of us here have personally witnessed, I would definitely not automatically assume that Tesla knows and watches absolutely everything as some of you suggested. They do have other things to do, you know.
