I live in such an area. With 2 exceptions, there is an area of just over .5 km2 (138 acres) where there are virtually no cars. I can let my kids out anytime.

I live in such an area. With 2 exceptions, there is an area of just over .5 km2 (138 acres) where there are virtually no cars. I can let my kids out anytime. It was built during the "million program" where the Swedish state built apartments for a shitload of people and elevated the living standards for about 2 million people. For some reason it is not considered a nice area, but in many ways it is heaven. I can bike to work in 12 minutes. My son's preschool is just 5 minutes away by foot. We have a moderately sized grocery store and a pharmacy within crawling distance. All areas in the "million programme" are not like that, but one pretty general idea was that since people living there didn't have their own garden they should have access to ample green spaces.
