I think traditional, walkable cities are a great idea whose time is more than overdue in North America. Places like Quebec City are a good example, but what really fascinates me is Tokyo, a behemoth of a city with so much that is walkable with one-way streets and wide sidewalk areas, and you can get to anywhere easily via buses and rail links. All these simple one-way streets, connecting to arterial roads with 1 lane in each direction, connecting to highways, create an absolutely massively distributed road system.
If you think i'm exaggerating, pull up Tokyo in Google Maps and pick a spot at random in the surrounding metro area and go to Street View, you will always always land on a one-way road, often with people walking on it.
