The typical adult living here makes in the ballpark of $20,000 a year and has a kid.
I don't think the town will pool together money anytime soon for a public works project.
The problem is that the desire isn’t really to curb traffic issues here. The existence of this ticketing setup serves several purposes, but ensuring the health and safety of the populace by reducing speed is only a secondary goal here, if even a goal.
Essentially they become judge, jury & executioner.
I find LA and OH's small town justice to be rather quaint, to be honest.
In short, the key thing about European speed cameras in my experience that makes them reasonable and effective is that they are actually designed and implemented as a way to slow people down, not as a moneymaking agenda
Side note I think Norway has gone just a bit too far with them. Especially in Oslo area
But you can still challenge it in court if you disagree. But you must be pretty sure it wasn't you, because there will be photographic evidence.
It is effective, but it might also be unpopular enough with the locals that you lose the next election. Especially if the measures inconvenience them.
I think the incentive for cities such as Fenton is a bit more specific: they want to fine unsuspecting strangers, who don't vote in local elections, while not bothering the locals too much.
You can interpret this as a modern, legal version of ye olde highwaymen. But there is a catch: transiting traffic is a genuine local problem (exhalations, noise, not contributing to local economy), so the incentive to make some money on it isn't as completely evil as it would be otherwise.
Except in this case there's a random aspect to the toll, and you can avoid the toll by knowing the situation and lowering your speed in time. I'm pretty sure the locals are all familiar with the situation and know how to avoid these fines.
If they really care about public safety, they would design their traffic situations so that people are less likely to speed. You can do a lot with clever traffic design, and it's more effective than simply fining everybody.
But of course that costs money rather than bringing it in. Considering traffic fines are their primary source of income, I think they strongly prefer unsafe driving over safe driving.
