The idea that cities should be designed around 15 minute hubs, where you should be able to walk to everything you need (job, grocery, school, hospital, restaurants, etc) within 15 minutes. From Paris's new plans to Barcelona's superblocks, it looks like cities across Europe at least are beginning to catch on to how appealing this way of living is. Thoughts on how to apply this to cities outside of Europe?
EDIT: The discussion going on here is fantastic and I love you all :heart-sickle:
The important part of the concept isn't a relative reduction in the travel time (quantity), but that if the time gets low enough the quality changes. Suddenly you can reach your quarter by food or bike easily, you are free to connect to people in your proximity.
