Say you're headed home from work, but you need to stop at the supermarket & pick up something for dinner. You're in a hurry: dinner is important. But there's a kid dawdling right in front of the frozen pizzas. So, naturally, you take your buggy & smash them out of the way. B/c that's what we do when we're in an important hurry.
Oh wait, it's not ok to do smash a kid with a buggy? Even if they're in your way?
Then why do we act like it's ok to do it with a car?
