This doesn’t seem to disagree with David’s argument? “Accident” implies a lack of negligence. “Not taken seriously enough” points at negligence. I think you are saying that non-negligent but “painfully obvious” harms that occur are “accidents”, which seems fair. David is saying that the scenarios he is imagining are negligent and therefore not accidents. These seem compatible.
I understand David to be saying that there is a substantial possibility of x-risk due to negligent but non-intended events, maybe even the majority of the probability. These would sit between “accident” and “misuse” (on both of your definitions).
