This downhill, winding stretch of road is 2 lanes each way with a landscaped divider. There is a golf course on the right and residential on the left, but no driveways enter Los Rios Blvd. The posted speed is 35 mph which is 12 mph under the traffic survey data which is supposed to be used as the speed limit. The cops sit at the bottom of the hill just past the golf course in the center median with their radar gun and waves you down as you approach him coming down the hill. The city of Plano knows this speed limit is not legal, but rely on the "home rule" in Texas to continue to convict drivers contrary to state law mandating the speed limit be the 85th percentile of the traffic survey speed. This area is artificially posted low just to write tickets and collect revenue.
