Why do you feel That Tesla FSD is "buggy shit"? No, it's not perfect, but it is mindblowingly amazing. At the current state I'm quite happy with what I paid for it. I've driven over a million miles in the last 35+ years, it's quite nice to have my car drive me now.
I don't know, watching cars teleporting around doesn't I still me with confidence. That's just the most surface level problem I saw during my brief experience.
