When I was young, I walked to school starting at age 6, and I walked to kindergarten even earlier. (And I played naked in the garden, in a small swimming pool with neighbour's kids (all genders).) It was also no problem to be sent to buy cigarettes, which in hindsight, I find less OK...
Today, parents drive their children to school by car, in walking distance. I don't know how they have time for that, but they cause traffic jams they then complain about.
From here, I am sure we will get a situation like in the US where parents may get into trouble if they give their children some independence.
And from there, the US now gets laws that make it reasonable again to give some independence. Which will follow here, too, I am sure.
It is very interesting!
