Sounds like what was done in Lahaina to make way for their “Smart City.”
“...just 200m (656ft) wide and 170km (106 miles) long...”
Seems like an odd shape. Even with a bullet train it doesn’t seem reasonable. I’ll have to look into it.
A suburb of Seattle is wanting to get part of the suburb to become a “Smart City”. Another suburb is creating a “15-Minute City”. I think they are distinct types of “cities”, but one could have a “15-minute Smart City” as well.
I remember back in the good-ol-days when UN Agenda 21 was just viewed by most people as a crazy conspiracy theory some of us conservatives dreamed up.
