These question-answering AIs are often called Oracles, you can find some info on them here. Their cousin tool AI is also relevant here. You’ll discover that they are probably safer but by no means entirely safe.
We are working on an answer for the safety of Oracles for Stampy, keep your eyes peeled it should show up soon.
In the field of road safety, the term “accident” is being depreciated. My understanding is that “It was an accident” suggests “It wasn’t done on purpose, I didn’t see it coming and I shouldn’t be blamed for it”, as a child would say to a parent after breaking a vase through negligence. In my mind, people get blamed for failures, not accidents, and your example sentences suggest someone attempting to dodge the responsibility for their actions.
With this framing, I can’t currently think of an event that I would label “an accident”, although “an accidental collision” would make sense to differentiate it from a collision that was done on purpose.
