From the very beginning of self-driving people have been making this claim that supervised systems would cause complacency that would make them perversely less safe. A lot of people believe it, but it's always been just an opinion based on speculation, not data. It's actually an empirical question. The data is in and this claim is definitively disproven. There is no increase in crashes when people use FSD. Not back when it was actually bad, not recently when it was just OK, and still not today when it's actually quite good but not perfect.
