In July, Mayor Bill de Blasio said the car-free 14th St idea would be looked into, a notion that the MTA seemed to echo last month. MTA spokeswoman Beth DeFalco told the New York Daily News the exhaustive process of "mapping out traffic flow models for the city and models for ridership overall" would be completed next spring. So, to speed things along we put our heads together to imagine exactly what a car-free 14th St, particularly around Union Square, would look like. Would there be food cart wars between all the halal and hot dog stands? Would pedestrians have to fight their way past street hockey, chess players, and even more "Free Hugs" guys than normal? Left subway-car-less, would the Mariachi bands and "Showtime" guys take their craft to the streets?
