Only on HN could someone be arrogant enough to think their non-experience is more accurate than another's actual experience.
At no point was anyone—myself, my child, or another party—in any danger. Perhaps that would be different for someone who had never used Autopilot and didn't know how to disengage. But after a year driving that car, I'm comfortable in my assertion that the situation was safe.
But, by all means, please continue with the HN pedantry. We wouldn't want this place to change.
not sure you're qualified to make that assertion, simply based on the series of choices you've described yourself making here.
