Oddly, I did this to my son a few times. I never thought that someone would call it in.
I occasionally tried to throw the girls out of the car. No one reported me either.
Within the last month, a "missing child" alert went out all over Kansas City right after school had let out for the day...seems a witness described a young boy being forced into a white, windowless van by an older man. Other witnesses had also heard screams....the city was terrified for hours of what might be happening to the little boy.
Finally, after the 10:00 news, a report came across that the boy was ok. Until the father watched the news that night, he had no idea that they were talking about him and his little incident with his unruly son that afternoon. True story.
