It's actually only a problem if it's the other way around, isn't it?

If kids run into a car, they will most probably just bounce and continue, perhaps inflicting some minor damage. But if a car mows down a kid, that could well be a fatal injury. Leashes for all the cars! ;)

A kid running into the side of a car that’s moving over a certain speed will be lucky to break only a few bones.
