You’re not supposed to blindly trust any of those. Why would FSD be an exception?
Because that's how Elon (and by extension Tesla) market it. Full self driving. If they're saying I can blindly trust their product, then I expect it to be safe to blindly trust it.
And if the fine print says I can't blindly trust it, they need to be sued or put under legal pressure to change the term, because it's incredibly misleading.
