Any child in that situation?  How do you know their situation by 10 minutes in a car?  I understand concern, but nothing happened to those children.  Concern is wonderful.  Overreaction to a situation is not helpful.  Perhaps vocalizing concern to the mother would be a good thing, but to make this a legal issue would be sad indeed without knowing more about the situation.  Chances are, these kids have good lives with a good mom.
