Car Sharing, bikes, self driving cars are part of a long shift to fewer cars per person

The Guardian UK has an article about cities can outgrow the automobile.

There are technologies and policies which can reduce the use and need for automobiles. These would need to be combined with urban design and planning to reduce the usage of automobiles.

The USA has about 809 cars per 1000 people.

There are some modern countries and cities in Asia and Europe with 300-500 cars per 1000 people.

Hong Kong has 77 per 1000 people and Singapore 149 per 1000 people.

Hong Kong and Singapore achieved good wealth per capita and low car usage with a lot of skyscrapers and high rises and high costs to own a car (parking spaces have massive costs in Hong Kong and Singapore has big fees for buying cars).

More skyscrapers could be achieved with lower cost factory mass produced skyscrapers

The Sky City design is a 200 story building that would cost about as much as an 80 story Trump Tower Chicago.
There is a design for a 600 story Sky City. A 600 Story Sky City could hold 250,000 people and have 2000 to 5000 square foot condominiums inside.

Currently the biggest car free areas and populations are in ancient cities like Venice. Generally 80,000 people or less.

There are car-free movements. There is a case for going car free or reducing cars per person to improve the environment.

China’s Broad group built acomplete 57 story skyscraper in record 19 days which means 3 floors in a day. A 57-floor 2-million-square-foot (180,000-square-meter) skyscraper fully built with energy-efficient, factory-produced Lego-like blocks. They are now building these at a record three floors per day.

Cable free magnetic elevators could be built to go between and inside buildings

Operating on the basic premise of a circular system, such as a paternoster, MULTI consists of various cabins running in a loop at a targeted speed of 5 meters per second, enabling passengers to have near-constant access to an elevator cabin every 15 to 30 seconds, with a transfer stop every 50 meters.

Schierenbeck said, “Per year, New York City office workers spend a cumulative amount of 16.6 years waiting for elevators, and 5.9 years in the elevators. This data provides how imperative it is to increase the availability of elevators.”

Increased bicycle usage helps cities reduce car usage

Uber and car sharing can reduce the amount of cars

Self driving cars would boost the trend to Uber

Tesla is providing autopilot for its cars.
