Earlier quoted context omitted.
Serious question: So why are all the people who are trapped/kidnapped in the cars in the movies not able to come out and have to yell to have someone come and rescue them? That implies that there is no way to open the latch from inside and people, including me, may take that as the truth and not even try to find the latch. I for sure didn't know that there was a way.
For some reason, the law requires the latch to be removed if the car is in a movie ;)
However, I'm truly shocked that someone asked "how come in a movie...".
