When the Williamsburg Satmar Rebbe Zalman Leib Teitelbaum left Brooklyn to visit Israel whose statehood he does not acknowledge, he was escorted by a large motorcade with flashing emergency lights and sirens. These cars drove erratically and unsafely and broke the speed limit as they tried to keep up with the rebbe's car. All of this is illegal. But in New York City, legality is a very porous thing.
