@BrentToderian The thing about Amsterdam is that it wasn't just a past decision - it is a decision they continue to make every day, every year, collectively.
I live part-time in central Amsterdam, and every time I return, I am amazed at the continued progression toward fewer cars in central and the continued improvements (fixing canal walls, bridges, etc). There is a long-term plan to eliminate cars in the central - and they progress toward it every year. The involvement of residents (we get to vote about improvements and are always informed of any construction) is paramount. And the public will - and continuation from one mayor to the next - never seems to waver.
