It doesn't matter if you hide the number; at some point they deanonymized you when you signed up.
Want to be a dick about "hoops"? Get a number that isn't traceable. It can be done, but it's tough. I doubt its possible in the countries that really need anonymity of association.
Speed bumps and chicanes aren't millions of dollars. In older neighborhoods with straight streets, block off straight shots and make people drive around to get through; that prevents shortcutting. Bollards and rubber speedbumps are hundreds of dollars.
I'm cynical; I think municipalities depend on photo radar for revenue and aren't actually going to do what it takes to slow people down when they could get money instead. And if I were really cynical, I'd say the camera companies put them in on percentage, but I can't confirm that.
IDK where you live, but where I am you get demerits and after a certain number you get a suspension and need to take a course to get your license back. But cameras don't count to demerits, so if you have enough money, speed away. Taking that money for cameras and putting cops on the ground handing out demeritable tickets would accomplish something; cameras do not.
I switched from a Pixel 4a to a Moto Razr when the 4a lost support, because I wasn't going to go any bigger than the 4a. Wish it had a custom ROM like Graphene though.
I've actually been really happy with the Razr for size and screen protection when folded. Haven't broken it yet and that's a record for me.
I don't get cameras except as a way to get fines money. If you wanted to actually slow traffic, you'd spend that infrastructure money on calming measures that work immediately and constantly. Cameras take effect weeks after the offence (in a small number of people) and only serves to make people watch for cameras instead of the traffic around them. Cameras have a very small area of effect and only for people that see them or know where they are.
If the point is just to punish speeders, make money, and not fix the problem, then by all means, install a few cameras.
I swear, he puts that "Thank you for you attention to this matter" in there just to piss me off.
