> In 1971, 80% of 7-8 year olds travelled to school independently. By 1990, it was 9%.

I feel for these kids. That time finding my own way home as a child was precious to me. It was my time. I was responsible for myself. I imagine you don't get a lot of that sort of time as a young child anymore. It's incredibly valuable - an opportunity to take and learn about risks (groups of young kids are actually really good at looking out for each other). A little chance each day to discover a bit of what the real world is about. A chance to be a member of your community on your own terms (dropping into shops along the way, putting a few coins in the arcade machine, greeting people you'd see regularly, etc).
