Yep, which is why I said it becomes difficult to determine priority, something which drivers often are given slack about, but computers might not get that same freedom. That's assuming your family is inside. What if it's you and your golfing or drinking buddies? You still want the car to put priority on its occupants over an outside child? Moreover, what if it's your own child darting into the street to try to say goodbye to you? A human driver is going to do anything to avoid that child. But not a car programmed to always put its occupants first.
