There has been the creation of 'The Tourist Lane' in New York City. I don't know if you know this, but New Yorkers walk fast.
Improv Everywhere caused a scene at 5th and 22nd when they began to spray paint on the ground two designated lanes. The actors wore bright yellow vests as they labeled the lanes "Tourists" and "New Yorkers". To make sure everyone followed the rules, they directed each passer by to their designated lane. Surprisingly, everyone cooperated with 'The Tourist Lane.'
