im not discrediting you, but i think your narrow view of AP is due to lack of experience. Youtube user DaErik drove 1000+ miles on AP alone and only a few miles of manual driving. No issues.
I know I watching them all same as for Kim with Like Tesla they didn't have much problems with AP on their trip at all same as
Ashley Renne or Now You Know. Maybe you right, maybe I don't have too many miles with AP.
