It would bother me that she thinks it's funny. That might be a deal breaker. Maybe ask her if it'd be funny if the dad trapped her against the garage with the car. Maybe she doesn't recognize how scary it is, or maybe she just doesn't see cars are potentially dangerous? You can fix the former, you can't fix the latter.
Unless there's something about the situation that actually makes it funny.
I also think you're overly excited about what the dad did. There are plenty of jerks out there and he's clearly one of them.
