Btw. the US is probably more of an exception when it comes to children being driven to school. Swiss kids tend to walk themselves from age 5 to 6 upward, schools are usually within 30min of a child's walk. But Japan is certainly special thanks to very liberal zoning laws. Even in rural areas it's common to find warehouses and small shops right next to or beneath homes. Europe's laws are somewhere between Japan and the US, and so is the walkability. Turns out, just allowing humans to try things will make markets solve this issue.
