Traffic Cam

I spent some of my holidays running around Kenting and Alishan. I am not driving a corvette but I struggle with speed and downhill stretches of dry pavement. I saw a lot of signs telling me about the cameras, and the speed limit. Alishan speed limit is between 30 and 25 kmph, and impossible task with the turns and tailgators (tailgating?).

Has anyone else noticed this type of camera? It has that single purpose day and night, bird house style.
