I agree, and not just because busy streets are unsafe for kids.
Neighborhood != community. Imo with: - Lack of interesting nearby spaces - poor walking options (unsafe, unpopulated, unshaded) - poor transit options - growing options online - polarization
Families are less likely to spend leisure or errand time in/near their neighborhoods. And kids suffer for that.
