Two quick up-dates on post 24 (my city plan):
1) Hertz CEO just announced on TV that in London, NYC and Paris, Hertz will soon have many parking areas for cars rented by the hour. (~$6/ hour). You get OKed for membership in the car "renter's club," your coded key card, etc. - not nearly as advanced my 2D "horizontal elevator" with computer driving you to your destination in electric powered "autovehics" that never stop in route as there are no at grade intersections in my transport grid. (It has controlled access, like an elevator shaft, so not possible to hit a dog etc.) But at least Hertz has the sharing of vehicle cost among many instead of private single owner’s cars and much higher cost with traffic jams wasting both fuel and time. There will still be accidents also, until my plan is adopted. (Vehicle safety is measured by accidents/ or deaths per passenger mile. Few know it but the elevator is at least 100 times safer than other forms of transport.)
2) In post 24 I failed to make it clear that the transport grid and "block building" sides are approximately at 45 degrees to North/South so all sides receive some direct sunlight. Likewise it was not clear that the floor area of each level decreases to avoid mutual shadowing. (Truncated pyramid shaped buildings.) I.e. on every level there is a perimeter garden, so from high above the city, it looks like a forest or field of flowers and/or vegetable gardens with roughly rectangular transport gird cutting thru it. Why the city is literally green as well as environmentally green.
In keeping with FR's desire for "telecommuting" I noted that all block buildings are "cable wired" for the internet and TV (no ghost images from building reflections) but now want to point out that many will commute by elevator* and possibly a short walk or bike ride via the separate and covered (no rain) bike and walking girds. (Roof of the bike grid is floor of the walking grid.) I.e. 100% of commuting is fuel free. Trucks use advanced batteries and buses use flywheels. Why city is “fume free.”
If you have not read post 24, I encourage you to as a very green, fume-free, low-energy-use city with much cheaper, safer and faster transport is possible. The key to all this is the elimination of at grade intersections so the Autovehics never stop prior to your destination, which is always a center of block terminal and under computer control autovehics can travel close spaced at much higher than current average urban speeds.

*I think it is part of human nature to want direct contact, both at work and in play, not isolation in some “computer cubical”, even if it is at home. This is very dramatically seen in Sao Paulo’s bars, which overflow onto the sidewalks with tables and chairs. Often the side walk in front of one is so crowded with people seated and standing, talking, drinking, flirting, etc, that it is hard to pass yet the bar immediately next door is essentially empty. The very fact that bars exist also proves this – you can drink your beer etc at home much cheaper. I.e. “elevator commuting” is much more desirable than “telecommuting.”
