The reason I bring up the definition is that "AI" is defined so loose as to include dumb lawn mowers.

In my friend's case, he was mowing on a hill, braced to pull the lawnmower back, and jerked it back onto his foot.

Edit: Looked it up, the number of injuries per year for lawn mowers is around 6k [1]
