It really doesn't matter whether the driver should or should not be disengaging, there are many, many studies categorically proving that "allowing the driver to be mostly relaxed and not required, only to require immediate intervention in dangerous situations" is absolutely, empirically less safe. You can't just white wash it away by "oh well, it will get better". When? And don't mention a word about Elon's opinion on when. The guy has been promising "this year" every single year for nine years now. More realistic estimates have this a decade, or two, away, at the very earliest. And I have huge doubts that when it does, Tesla will be nowhere near it. Their phantom braking fiasco proves just how horrific Tesla's approach to testing is, throwing multiple releases out into the wild with less than 72 hours between them, for absolute safety features. Anyone who claims that those releases were subject to any form of rigor in testing whatsoever is deluded, and anyone claiming that testing it on the public roads is somehow acceptable is equally deluded.

I am very, very well aware of exactly what causes traffic fatalities. According to the software at my work, I have personally responded to 378 fatality MVAs as a paramedic. Please don't try to assume everyone is ignorant about realities - we are not blindered, and only physically capable of recognizing and responding to one danger at a time.
