As the Hudson Parkway southbound comes to its first light at 57th Street, the limit drops from 45 to 40. The cops are close to the traffic light on the right shoulder looking north aiming radar/laser up the hill onto southbound traffic. As this point is about a quarter to a half mile before the light, traffic is flowing above the limit, at about 50 to 60mph.

The cops are on foot and traffic can be heavy and fast. So they only ticketed the drivers on the right lane that they could pull over with a little flashlight, myself included. The drivers in the center and left lanes were faster but were not bothered.
