Are these living streets all signed as home zones? From the aerial imagery, they just appear to have a different surface and no pavements/sidewalks. Presumably they also have the default 30 mph speed limit of other restricted roads? They're the antithesis of living streets: the developer appears to have prioritised cars and made no provision whatsoever for pedestrians.
