Bike:Compact:SUV to pelletgun:handgun:rifle
Like I said, a bicycle is very capable of severely injuring or killing a pedestrian, which is why I group it together with automobiles. I'm not familiar with how powerful pellet guns are, so I don't know how that analogy applies. I suspect they are at least capable of causing severe eye injury, and I would encourage the exact same precautionary behavior with pellet guns as with handguns and rifles (trigger discipline, don't point at people, etc.).
I guess I'm a little confused by what point you're trying to make. If your preface was intended to invalidate everything you wrote after it, then it's my mistake for trying to do the same.
