Correlated but not exactly the same is being out & playing without adult supervision.
Kids being out and running into emotional challenging situations allows them to learn and deals with emotions & anxiety are very important for later life.
I've been thinking a lot about this. What age would you let your child go out on errands by themselves?
When I was 7, in France, I'd walk a kilometer by myself to go on errands like going to the baker. I have a friend living in Tokyo who let his daughter go on errands around 5 years old (but Japan in particular is very accepting of this). We live in Hong Kong, here, I think the age is more around 8 or 9 years old.
I rode my bike to school in Middle School because it was so close a bus didn’t come. When I started High School it was a 2-3 miles away but I continued doing it until I had a car.
My friends and I would ride our bikes or walk everywhere we wanted during the day from 11/12 on. We would ride to a pharmacy weekly and get a snack or a small item for my mom.
