They're hardly the same. A vehicle moving on a road is using that space exactly for its intended, accepted, and lawful purpose. A bullet moving through the air

They're hardly the same. A vehicle moving on a road is using that space exactly for its intended, accepted, and lawful purpose. A bullet moving through the air in a populated area is not. Accidents do happen; you can't make the world perfect because it is full of imperfect and sometimes irrational (like a 4 year old) people. Personally, I drive extra slow in residential areas just so I can hopefully prevent something like this from happening to someone's child.
