Part of the problem is that roadway rule enforcement is seen as the police's problem and the police's budget, which is probably why they were getting the revenue from the cameras in the first place.

The portion of police budgets that goes to traffic control, responding to accidents, doing radar, and issuing tickets should be considered part of the roadway budget. How we design, fund, maintain roadways and their alternatives directly impacts the funding needed to enforce roadway rules and respond to roadway accidents. It doesn't seem fair for speed enforcement not to be considered while designing the road then just dump that problem onto the police budget.
