How to design a city?

Does the idea of shared space necessarily have to rely on a certain degree of tolerance? Or does tolerance develop with 'acclimatisation' to shared spaces?

the answer is unknown and arguable. although the city of london has implemented a fair few with cyclists and pedestrain and it works whereas when mixing cars with pedestrains it has been less successful and, due to lack of ongoing political backing, they implemented traffic lights where shared spaces existed beforehand.
