Estimating individual Supercharging abuse-looking cases from afar is a bit like assessing moronic-looking individual behavior in traffic without actually being able to talk with the "moron".
In our isolated bubbles, separated from communication with the other party, we can and often do see things differently than the other person or their intent. We make a judgement based on limited data and preconceived notions.
Like right here on this forum someone assumed people driving away from Supercharger in another car were local chargers abusing the system and leaving the car there for an extended period. Yet we soon got an example of a case where, while it looked that way, it was perfectly reasonable use (two cars, an ICE and an EV, driving to a destination and using the ICE to quickly visit a rest stop during charging of the EV).
Sometimes from the other person's perspective the situation was quite reasonable - or at least human, without malicious intent or negligence - yet from afar it looks like terribly bad behavior given the limited data and existing prejudices.
I mean, sometimes bad looking behavior of course is just bad behavior (and sometimes bad behavior where there was no malicious intent, but there was negligence that should have been obvious), but not always.
I've often wished that in traffic there would be this "sorry, my bad" honk or sign, because sometimes you clearly see afterwards that something you did might have come across wrong.
