My Hero Academia 3: Villainous Interlude

[John Cribati]

If a person stumbles into me at walking speed, I'm inconvenienced for a few seconds at worst. If someone crashes into me at running speed, I'll probably be knocked prone. If someone crashes into me at flying speed, which for most people would be comparable to the speed of a bicycle or faster, I can be seriously injured. In general, I trust that the people driving know how to drive amd will follow certain regulations with respect to pedestrians, and if they don't and end up in a situation where someone is hurt, they're punished more severely for it. I would treat flying much the same way.

Also, just in general, people do have to learn how to walk, at least on a mechanical level. We aren't born walking, and we can assume people with wings wouldn't be born flying either.
