Yes, though I can't recall enough details that I could help you search.

Basically anytime it is tried in the suburbs where nobody is walking now nothing changes. When a lot of people are already walking you can increase traffic by getting rid of cars.

Details matter, most of the places people take aware cars are already dense areas and they tell you about it. However in a few cases someone who hasn't understood the context tried to apply a lesson it doesn't apply and it fails.
