Free range parenting - Dutch level

The general consensus here regarding parenting seems to be "Unless an appendage has been lost, I don't care what my child does". The parents really just don't seem to care what their children are doing. Many times, you can't even tell who the parent is because the kids have been permitted to wander far away from the parents.

One time I saw 2 women biking along the boardwalk with 3 children. One of the children, who looked to be about 3 years old, was on a little razor thingy (see image below)... FAR behind the adults. Neither of the women seemed to care or notice. It was almost like watching one of those nature shows where the momma animal is on the move and if one of her offspring doesn't make it then... oh well.

One mode of transportation for children not old enough to bike

A few weeks ago hubs and I were walking along the beach and saw a girl of about 2 or 3 years of age walking and crying, yelling "momma". We looked, no one in the immediate vicinity was reacting. We then spotted a woman about 50' away from the girl pushing a stroller who turned around and seemed to acknowledge the girl existed and was still alive. She didn't stop to let the girl catch up, she just kept on going.

Last year hubs and I went to a museum dedicated to antique and classic cars. One of the rooms contained fuel pumps that were quite old. We watched several children try their best to destroy the pumps. None of the adults in the room seemed to care. Turns out none of the adults in the room were the children's parents. They arrived several minutes later, not that it really mattered. They didn't seem to care what the children were doing either. No appendages were missing... no behavior to be modified or corrected.

I don't support helicopter parenting either, but if the parents aren't reprimanding the children for their behavior, who will?
