I'd say the bar for writing it off as simply an ambitious phrase is a bit different when you know that particular form of "user error" is literally lethal.
So far one person has faced lethal consequences. As the article states, that person was fully aware of how autopilot worked. Do you honestly think that if that feature was called something else that person would still be alive?

This is the tip of the iceberg.
How many other Tesla owners aren't fully aware of how the feature works and are just relying on the vernacular usage? Even if 100% of Tesla owners are 100% aware of the feature's capability, what happens when a friend/coworker/spouse/child of the owner borrows the car and uses the feature based on their misunderstanding of the technology?
