Arizona had fixed location photo radar as well, all it did was to cause backups approaching those locations. The portable ones had to be clearly marked about 1/2 mile before you got there. While they did catch some really stupid people (one guy going 135 mph drunk, it was so extreme they were at his house waiting) it did little for traffic control.Ontario Canada had photo radar on the highway for a while. It produced evenly spaced vehicles. Gone were the drivers that weaved thru traffic to gain 30 seconds of distance ahead of the pack......and that strange grouping causing dead stops vanished.
Change will not come without a lot of irrational kicking and screaming.....some people still refuse to wear their safety belts.
The Darwin principle seems to reduce those numbers.
I welcome the future. Evolution is good. Say goodbye to Dino-cars.
