I was thinking the same thing after posting! Shut pretty much the whole of Manhattan to cars, only allow bikes and buses. Goods vehicles can deliver during the night. Think of the reduction in noise, smog, stress, and people could get wherever they want so much quicker than they do now!

Don’t forget that Hawaii should go to Iceland due to volcanic brotherhood (and to give the Icelandics an opportunity to get a tan). And NYC goes back to the Netherlands if they’ll take it (think how expensive it would be to add all the bike lanes).
