>I’m not exactly sure why Tesla needs to call what English-speaking humans call “driving” the “dynamic driving task (DDT)”

My hunch is they do this to be more precise in terms of what the software actually controls.

Having previously worked in safety critical software roles, there were times when the team would get into disingenuous word smithing to avoid safety requirements. E.g., “the software isn’t ‘autonomous’ because it requires a human to make a destination decision at the onset”. In this case, using the word “dynamic” removes any ambiguity that the software is making continuous, time sensitive decisions after the human. Just calling it “driving software” probably isn’t prescriptive enough
