Car Free Day
While hundreds of European cities closed streets or entire districts for this year's car-free day, some capitals saw the scheme backfire causing large traffic jams.
"While there are a handful of car-free locations in the United States, including Michigan's Mackinac Island and Santa Monica's Third Street Promenade, the idea has been slow to catch on in this car-obsessed country. Just a few U. S. cities -- Madison, Wis., Decatur, Ga., and Portland, Ore. -- are hosting car-free day events."
