The problem with traffic cameras in the US was that they became outsourced revenue enhancement rather than public safety.

The cameras would get installed at busy intersections with lots of minor infractions to collect fines on rather than unsafe intersections that had lots of bad accidents. And then, when the revenue was insufficient, they would dial down the yellow light time.

Consequently, and rightly, Americans now immediately revolt against traffic cameras whenever they appear.

(San Diego was one particularly egregious example. They installed the cameras on the busy freeway interchange lights when the super dangerous intersection that produced all the T-bone accidents was literally one traffic light up the hill. This infuriated everybody.)
