Hong Kong is fucking awesome to get around. Why not moving sidewalks like they have there with the Midlevels Escalators? I used that to walk from Midlevels to Central every day and loved it.

Hong Kong has a population density of 6,544 people/km^2.

The United States has a population density of 35 people/km2.

NYC has a population density of 10,831 people/km^2.

San Francisco has a population density of 7,124 people/km^2.

I'm not sure what point you were trying to make, but I don't think anybody really wants to plan the rural areas of the US in the image of Hong Kong.
