I think this take is pretty BS. I'm not claiming sainthood or anything, but I don't drive like an insane person either, and every time I've driven a Tesla (which is at least semi often, my parents own one) it just goes HAM beeping at all sorts of shit, and it jerked the wheel weirdly on me at least once when it seemed to get terribly confused about what was actually a lane or not.
Moral of the story, the features are far from perfect, and I would prefer the number of times the car moves the wheel for me to be 0.
