His genetic examples look like European cities compared to the actual floor layouts, which are more like New World ones designed on a grid layout by central planners.

There is, it has been proven that on average, if you select two points in European cities the average distance by road, number of junctions etc is smaller than two randomly selected points in a grid system.

It seems like a grid system is superior if you have no knowledge of the city, but a "organic" european layout is functionally superior assuming people always choose perfect routes.
