Car Free Cities

I hope that more cities in the fugure will be designed to be car free. Here is a website that describes the concept of a car free city:

In Singapore, we can apply this concept to the new towns that are being developed. All movements within the town will be by walking or public transport. People should be encouraged to live, work and study within the same town.

Here is my idea of how the future town should be developed:

With the high price of oil and the damage to the environment, this concept becomes more urgent in all cities around the world.
