Obviously wrong, does it look like a Built-in Speed Camera to you, or as it is represented lately in LUNA, Camera in Traffic Light?
Because then that's the icon that appears on the navigator.
Everyone is free to catalog it as they see fit, in Italy it is included among the Overtaking Detectors in the Forbidden Area, I could also create a new category, but it seems a bit too much for only 4 cameras around Milan.
