You believe that do you? And if the car had been stolen? You think a dog is going to stop a gun? The child was safe by the grace of God, nothing less.
And what if there was an earthquake or a tornado? What if zombies attacked? What if bank robbers took the child as a hostage? What if a tsunami came and wiped out the whole town? What if Ents came to life and stomped the car?
Playing “What if...” is a straw man, and a silly, annoying one at that.
