I love these streets

Well there's still a fun game cars can play there it's like bowling

This is an amazing idea! I never knew people did this. I love it. And it looks like there are nice little shops, maybe bookstores and cafes and places where adults can sit and talk or play cards or dominoes or whatever and watch the kids play. I can imagine kids playing music and having little dance battles too. The kids would benefit from the older people's wisdom and cool stories and the elders would learn from the younger ones new slang words and music and dance moves lol.

why is it still a paved road then?

I feel like these streets should be parks, and cars and bikes should be able to use paved roads like this
