They are asking for a modest plan of banning cars from all of Central Park for 3 months next Summer to prove to the city that traffic patterns will adjust easily. In fact, there have been plenty of recent examples when cars have been banned from Central Park, such as when "The Gates" were on display this February. Traffic increased only slightly around the park and even declined in some areas during those few weeks. A planned closure of the loop to cars during the Summer months would allow drivers to adjust over a longer period of time to the new traffic patterns. But the benefit will be a park that will be used for its intended purpose - a place for reflection, relaxation and recreation.
