Right, that's true.
No, you didn't imagine it, but you made a faulty assumption about what the change was.
There have been some steps of significant improvements of both the steel chemistries and certain coatings of the steel used in cars that fend off rust for much longer.
I think there is a point you are not getting though, which
@father_of_6 reiterated:
Back when things were more rudimentary, we had to pick our charging stops, and we KNEW we had to pick our charging stops, so we picked appropriate ones. It was fully understood we had that responsibility from start to finish.
Then, Tesla implemented a function that says, "I take care of that so you don't need to anymore." So then the car says it's doing it, and people expect it to do it. But then the car does it wrong. That is even worse than if they had never even created that function at all, because it's creating the false expectation that it's being handled.
