They botched the rollout.
When you introduce new technology you have to get buy in from the users. That means transparency (open publishing of error models, printing speed error on the tickets issued), warning periods for a driver during which tickets are issued but without payment required (eg first ticket is a warning), and there should have been regulations against municipalities putting them everywhere, even in places that were nowhere near schools or other CSZ buildings.
If they had put in a bit of care, they could have built goodwill without giving the impression right out of the gate that it was a cash grab and if you contest it or ask for details, it's "trust me bro".
