@Aslanmane @gabriel @fu The freak out about 15min cities began when Oxford in the UK did a trial. And as part of that trial, they closed down roads between different zones. So to go from zone A to B you had to go the long way round via the highway. In this way they could track when you left your zone. From this people extrapolated to all the things Gabe mentioned. So banning cars isn't the first step, it the future potential step.
