I think the problem with the "it works for me" type posts is that most people reading them think the person writing it is trying to refute what the person with the problem is saying. As in, "it works for me, so the problem must be with you, not the car".

I will refrain from commenting on whether or not that's a fair assumption to make, but I think that's where the frustration comes from.

I think when people make "WFM" posts, it would go a long way to acknowledge that the person who had a problem really did have a problem, even if implicitly.

"That's a bummer; I've driven thousands of miles using FSD, and I've felt safe and have never had to intervene. I wonder what's different about our travel that's given us such different experiences."

That kind of thing would be a lot more palatable, I think, even if you might think it's silly/tiring/whatever to have to do that every time.
