2nd, it appears that the car was posed and photographed by the same photographer form 4 directions, and that gives a real good view around the car at what else was happening in the area.
How about the knickers on the cop near the car, and the heavy long coat on the other cop... which brings me to the prominent umbrella the traffic cops were stationed under while they turned the stop sign to direct traffic. No red, yellow and green lights to get traffic slowed down before coming to a stop, nor any time delay between the cross traffic getting into moving through the intersection once the "stop" order was given to traffic moving through the intersection
