@David Megginson is this a residential neighbourhood so quiet that pedestrians can (and do) actually safely walk in the middle of the street, only moving to the side once or twice when a car happens to arrive (and if they are slow at doing so, the car will wait)?
we do have places like that around here, and I agree that they don't really need sidewalks, especially when the streets are already quite narrow as they tend to be around here.
anything less that that, yeah, sidewalks, thanks.
