Julien Bargeton, deputy mayor in charge of transportation, said the city needed to move past the car. “In a dense city, the car can’t be the favored transportation mode,” he said. “There is room for cars in the city of tomorrow, but they can’t take up all the room, as they do today, with public spaces that are widely reserved to car traffic, even though 60 percent of Parisians don’t own a vehicle.”
