I (distantly) knew someone who was cutting grass on an incline adjacent to a pond. The lawnmower flipped, and it pinned him in the pond. He drowned in a foot of water and was sober.

People misjudge things all the time. I would guess it was a combination of distraction and/or non-ideal terrain (slope, dropoff, or combination).

It’s rampant click bait. I try not to reward the behavior with clicks, but sometimes I’m genuinely interested in the topic. This is not one of those times.
