Extend the Corso no car area to some more streets.
I saw a city in California on TV recently that had a large planned no car area and it looked good.
Spot on! More walking by those who live in and visit Manly is good for everyone! The resident who gets his or her exercise - able to beat the 10,000 paces a day recommended for good health. The visitor who sees and values more of Manly the world-beating beach resort (with ocean and harbor beaches) The shopkeeper who has more eyes lingering on his or her goods or services followed by purchases!
I am all for the new car park
