Precisely. People can harp on about &#x27;oh but it says to pay attention whilst using it&#x27; and &#x27;oh but it&#x27;s still in beta&#x27; all they want, but good engineering in the real world, where <i>shit kills people regularly</i>, means engineering out all possible human-machine failure modes.<p>This is the result of applying &#x27;she&#x27;ll be right&#x27; cavalier software engineering attitudes to real-world engineering (civil, mechanical, structural, etc.) because in the vast majority of cases, software engineering is completely erasable and is fixed with a simple refresh. Agile doesn&#x27;t work in the real world. It hasn&#x27;t ever worked in the real world and that&#x27;s why waterfall approaches and FEED is so engrained - it&#x27;s proven to be the best method to avoid killing people and creating garganutan cock-ups.<p>Tesla should not include features that are &#x27;beta&#x27; in a car. Tesla should not include features that promote inattentive operation of the vehicle if they are not absolutely, several-sigma robust. It doesn&#x27;t matter how many disclaimers you slap on it or how cool and futuristic it is, the feature fundamentally encourages people to stand away from their vehicle, press a button, do something else and have it magically arrive next to them. This is bad engineering design no matter how you try to spin it as &#x27;innovation&#x27; and doesn&#x27;t cut it in the real world.<p>edit: The entire aviation industry is a textbook in this concept.
