I think a lot of automated policing would help in the streets. It's probably not a popular point of view, but so many people don't care at all and nothing is enforced. Cars driving like it's real life madmax. Cars driving without license plates. People running red lights. It makes the streets the wild west and a lot of much worst crimes happen as a result of it, since once someone is gone from the crime scene, very little happens to them as they blend in a sea of lawlessness on the roads.
An effective way to avoid the automatically issued ticket.
The problem - as I see it - with this kind of automated speed (or red traffic light) tickets is (given that the car is correctly identified by its license plate) that they arrive days, weeks or months after the event was recorded.
So they have - at the most - a very late effect in educating the drivers.
Additionally they may well (if not properly regulated) become a sort of "trap", where the local municipality puts one of these in a stretch of road/street where an artificially low speed limit has been posted or at a traffic light where the yellow light time has been set to a minimum, in order to get as much money as possible from the foreigners (the locals would quickly learn).
The purpose isn't educating drivers, safety, or whatever. The purpose is money.
Like red light cameras, they don't reduce severe accidents and injuries at the expense of causing a lot of minor ones. But they do generate revenue and soft bribes for public officials.
