The reality is more complex, and as usual, LE managers (few are leaders) have done an awful job of explaining that. Look at the all the false discourse about "mass incarceration", use of force, etc. It really gripes me.
It took me a few years, but I learned to drive in a manner compliant with the traffic laws and haven't been stopped or cited for so long I really can't recall.
In some states, tickets generate significant revenue; here they do not, and are closer to a money loser than revenue. I started in LE in a state in which the revenue mattered, but I did not write chippy stuff. I allowed 9 over at the point which people came into town, and because of a railroad bridge, one had to WORK to be going that fast. I could easily write a ticket 4-5 times an hour. I wrote several for 20+ over; some were for a lot more than the speed limit outside of town. When I left there, they had a little kid killed in a crash by such a driver.
In the City in which I reside, the local agency had a Chief for several years who really discourage enforcement, and it showed. A few years ago, I regularly saw one nitwit who drove all summer with his studded tires on and never got caught. One officer I know had his tint meter taken away because he actually used it. The driving behavior in general is abysmal - one real annoyance to me now is the number of people I see who don't have their headlights on in fog, on gloomy days, etc. Traffic safety is a big deal - crashes are one of the most significant forms of easily preventable death (almost all are homicides, most criminal). A disproportionate number are caused by people who are already suspended/revoked; one of the best ways to catch them is the most are just crummy drivers and commit. lot of minor offenses.
Also: vigorous traffic enforcement was shown in a study in the mid 70s to be the best single manner of finding and catching criminals and reducing criminal activity. I have looked repeatedly and never found any study coming to a different conclusion.
Are there places that are out of control? Sure. When I was trucking, Stringtown OK was well known. I still remember that, over 25 years later.
