Amsterdam is just like New York (New Amsterdam!) in that pedestrians (and bikes) cross wherever they like. Next up: in Amsterdam most bikes and pedestrians will not wait for a red light on small crossings when they can see there is no oncoming traffic. Technically illegal but I've never heard of anyone being fined. No harm no foul. But I guess the large intersections in New York make it trickier to estimate whether that's safe to do.
