Really neat visualization. Would love to see it for other cities (perhaps Paris would be a good one for comparison, since it's touted as the fifteen-minute city par excellence).
Strangely, I live with my wife and daughter in Boise, Idaho and we don't own a car. The high school, my work, grocery stores, etc. are all within a short walk.
It bums me out that we had that taken from us. I'm glad you found one of the places where you can still make it work!
