I guess the thing I'm trying to reconcile is that even very safe drivers make critical mistakes extremely rarely, so the threshold at which FSD is safer than even the top 10% of human drivers likely includes some nonzero level of critical mistakes. Right now Tesla has several people mining FSD for any place it makes critical mistakes and these are well publicised so I think we get an inflated sense of their commonality. This is speculation, but if true it leaves some possibility of it being significantly safer than the median driver while still allowing for videos like this to proliferate.
I do wish Tesla released all stats for interventions/near misses/crashes so we could have a better and non-speculative discussion about this!
