Slightly OT, but I've been wondering for a while now if and when license plate scanner camera data will be compared and analyzed for traffic violations, like "you went from Park Ave to Boardwalk in a time frame which would have required you to exceed the posted speed limit, here's your ticket".
We're still fighting in Taiwan over whether or not average speed cameras are legal in Taiwan.
There's a couple strong, imo, arguments against the legality.
For one, average speed cameras are constant, identified surveillance of everyone that drives passed them (as opposed to CCTV, average speed cameras positively identify every vehicle that passes by). Blanket surveillance is bad and possibly illegal, but also it happens to civilians the State has no reasonable suspicion have committed a crime, which is also bad and possibly illegal. Finally, a ticket gets written for someone breaking the law by driving faster than the speed limit... but in fact, nobody, including surveillance, actually witnesses them breaking the law. They just assume they broke the law because timestamps.
I know it sounds silly but it really is a pretty big legal leap to "assume" someone broke a law without actually witnessing the crime itself. You might suggest the timestamps are strong evidence of the crime being committed, and sure, you're right, but then we're back to the blanket surveillance issue. Furthermore, there are actual ways to pass two average speed cameras within a time frame that would "require" speeding, such as by taking a route unaccounted for in the camera's design.
Though in the end the cameras are pretty useless because they put them in the best fast riding zones in the mountains so we just zip back and forth between two cameras practicing the same route a couple times at 3 or 4 times the speed limit and by the time we go past the second camera our average speed is like 20km/h lol. Whereas regular actual speed cameras at the entrance and exit of small towns actually force you to slow down for pedestrian-heavy or dangerous areas.
I've had an argument with some police politician about this, about how putting the cameras in the good riding areas is pushing people away from the safest riding spots in Taiwan with wide shoulders, double lanes, and barriers between oncoming (SO COMMON for cars to violate the double yellow here!!) and into the single lane unlit nightmare roads alongside the big good road, which are impossible to get speed camera infrastructure to (without great cost anyway). Which is driving up deaths so really defeating the purpose.
Or, roads are a community utility and a community playground? I don't understand why one usecase is automatically more valid than another. We're discussing the old mountain roads. People trying to get between Yilan and Taipei quickly do it through the new tunnel which takes less than half the time. Basically the only people on the roads I'm describing right now are enthusiast motorcyclists, scooters, and sports cars.
On a trip from Kristiansand to Oslo in 2011, I noted to the driver of the vehicle in which I was traveling how unusual it seemed to me that no one on the highway was being impatient or aggressive. How remarkable, I proposed, that even the impatience of motorists could be tamed by Norwegian social norms? He chuckled and explained section speed control to me: https://www.vegvesen.no/en/fag/fokusomrader/trafikksikkerhet...
Norway has the lowest per-capita traffic deaths of any European country. Check out the US's traffic death statistics if you need another reason to be disappointed in the outcomes of our domestic policy.
If it doesn't catch a picture of the driver it most likely will not valid in court in most states.
Be fun to troll the shit out of politicians/elected officials with this. Have someone monitor them leaving one place, then with another car and a fake plate have them get scanned at another location moments later.
In my experience the cops using these systems only care about larger crimes. It's way too noisy to monitor every expired tag, for instance. Not many of these companies (if any) do speed monitoring with LPRs.
But what they will do (and have done) is pull over a vehicle that is registered to a person known to have e.g. an expired/suspended license and use whatever excuse they can find to arrest the driver, even if the driver's license is not expired.
The near-real-time cross-referencing is basically a probable-cause factory, and then its on the person getting pulled over to stand up to all the implied threats of violence that the police can bring to bear.
Prior to tools like this, running a dragnet on e.g. invalid licenses was quite a bit more labor intensive, and so there was a built-in grace allowed to people whose only crime was omission of paperwork.
