It's not they don't work to decrease speeding... They do. It's that if the point was immediate deterrence there would be some feedback to the driver they just got a ticket, like the kind of immediate feedback you get when you are pulled over by a real cop.
Lol no the only purpose is increasing revenue via fines.
If it was a real safety deterrent there would be some immediate feedback like a text message, assuming you have your phone number in your driver's licence registration. Instead oblivious drivers will be going too fast in that stretch of road for weeks before getting tickets in the mail, and then they'll get a bunch of tickets.
The point is to hit them with the fine 5+ times not once.
I didn't read that as "you are a rapist", I read that as "this is the same kind of non-empathetic and hostileness that rapists display" and implied "do better"
So I get why you feel attacked but it's a legit criticism
