I don't actually see the point of creating such a category. Accidental deaths has a whole bunch of sub-categories that are covering all sorts of causes, but how useful most of them are I am scratching my head about. I can see things like rail and plane crashes being useful, since in one event many can be killed, but accidents while riding a horse, or having a tree fall on them, it's like, what is the point of linking them under a category? Such can happen all over the planet, being disrelated incidents.
