I'd argue that Paris actually represents the epitome of what the OP detests in cities because they actually replaced narrow, winding alleyways with broad boulevards aimed at road transport.

It's also a clear example of why the author's theory that street width is all important is wrong: central Paris is still very walkable with an incredibly strong sense of "place" because of the broad boulevards rather than despite them, whereas plenty of the "walkable" streets he highlights are either cul de sacs in suburban areas or pedestrianised zones in town centres usually accessed by car.
