Isn't the intent in this case the same? Wether or not the object that she hit was inanimate or something breathing (ie. human, dog, cat, etc.)?
Not really. Your car, cat, dog, or pink flamingo lawn ornament are considered property. Different laws apply.
Speaking of intent, this girl's intent was to learn to drive. her father's intent was to teach. No harm was intended. She lost control of the car and he failed to retain control if the situation. He is civilly and criminally liable for this young mother's death.
