This is not remotely close to entrapment.
Indeed, nothing forces, but things really strongly suggest through the use of psychology. The mafioso didn't force you to be a drug mule when he said he'd murder your family if you didn't. The website didn't force you to let them sell your data when they put in giant bold letters "AGREE AND ENTER" and in 5 point grey on grey "decline" -- after the website's owners ran multiple rounds A/B testing to see what was most effective at getting people to click the option that gives them free money. They didn't force you, it's all your choice buddy. You feel tricked or conned? Like you were carefully goaded into making a choice against your best interest? Well, you shouldha read the small print, sucker!
Anyway, I don't think these things are "entrapment" (meaning the police coerce you into breaking a law you wouldn't otherwise have broken), but they are sketchy, especially if the organisation in charge of enforcement also gets a cut of the fines.
Your example reminds me very much of Brookside, Alabama, where the tiny town's police department did everything in its power to bilk passing motorists for its own private enrichment. https://reason.com/2026/10/01/judge-preliminarily-blesses-1-...
> Brookside "recognizes" that its "policy of aggressive policing," which "prioritized generating revenue for the department's expansion," "likely interfered with the Town's obligation to administer justice equally under law," "undermined the public's trust in the justice system," and "raised serious constitutional concerns under the Due Process Clause of the Fourteenth Amendment."
Uh, yeah it is? This is literally textbook coercion through threat of murder. I'm not sure how this is relevant to people who don't pay attention to speed limits and speed, though.
Also, the example in your linked article isn't even related to speed limits:
> According to the lawsuit, Coleman "was following three or four car lengths behind" her boyfriend's car. But Sellers claimed she was "tailgating." He also claimed to smell marijuana, which supposedly justified ordering Coleman out of her car and handcuffing her.
You can slow people down by making lanes thinner, adding in-road obstacles or chicanes, removing road markings to take drivers out of their complacency and get them actively thinking, and at the slowdown at the end of a road, using tightly packed lines or rumble strips to give the impression of speed, to which they naturally react by slowing down. You also stagger junctions, and put in bends, rather than have a fast road run directly onto a slow one (or vice-versa) and then say to yourself "WELL, I DID MY PART, I MADE A NICE FAST ROAD SLAM RIGHT INTO A SLOW ONE, AND IT'S ENTIRELY ON THE DRIVERS TO NOTICE THAT STOP SIGN AND SLOW DOWN IN TIME. NOT MY PROBLEM IF THEY DON'T"
Naturally, if you do the opposite, and build a wide, long, straight road with few visual indications of how fast people are going, even the most conscientious will likely zone out and start unintentionally speeding up. It's simple human psychology.
You can't be like "human psychology's not a thing, I'll judge every single human like they're completely omniscient and perfectly rational", because there are millions of people who unintentionally do things they don't rationally want to do, every single day, because they were psychologically manipulated. Use road design to manipulate them into doing the right thing, rather than manipulate them into doing the wrong thing and then directly take money from them. That's a dark pattern.
