> My parents told me later that they secretly followed me the first few times (I never noticed).

Ha, not in the Netherlands, but we started doing exactly the same with our 5-year old recently. She wanted to walk to a friend's house alone a few weeks ago and my wife followed her in spy-like fashion to make sure she arrived safely. We also started dropping her off a few blocks before kindergarten so that she can walk the remaining distance "alone" (again secretly followed).

That is how it worked when I was a kid on the 80s in Spain. I took the bus to school alone as an 8yo -- and I was considered a wimpy kid; my sister walked to school alone at 6.

Meanwhile here in Canada they attach colored ribbons on their backpacks so they won't be allowed off the bus unless an adult is there to escort them home. Watching a 10yo being escorted back and forth to the bus stop is so sad.

Personally, I blame the speed and amount of car traffic in our streets. Drivers routinely break the speed limits and oftentimes by the time they come to a stop they are already blocking the crosswalk.
