Man gets 30 days in jail for drone crash that knocked woman unconscious

If an operator logs a bunch of practice hours but makes a mistake in a crowded area and collides with someone, is that negligence necessitating this sort of punishment?

If the device isn't badly maintained but has an unexpected failure and collides with someone, is that negligence?

Now read those questions again with a different context, say "bicycle" or "skateboard." Statistically speaking, if drones are much more likely to cause injury than bicycles, maybe there needs to be laws. If not... well, I'm not sure it's expedient to ban everything in order to save the children.
