In 2023 and 2024, Flock sent 1,427 alerts to the Roseville [CA] Police Department.

Roseville police found that Flock misread license plates in 71% of those alerts.

Max Isaacs, director of technology law and policy with the Policing Project at New York University's School of Law, described Roseville's misread data as "stunning."

"A 71% misread rate is really beyond the pale," he told Business Insider, referring to Roseville's reported error rate for stolen and felony vehicle alerts. He added that "in the absence of concrete rules that directly address the problem of misreads, this technology is not safe to be deployed in communities."

For a Trump admin approved device, we're all shocked it read that well

Get those criminals off the street.

If it's the responsibility of the party that's been misidenified to correct the mistake, this was intentional. Putting fines to random people, knowing a proportion won't fight it, is a foundationional pillar of Authoritarianism. What's worse is even more work will now need to be done to undo and correc this, because it's already in place. The lawmakers will try to get the percentage up, instead of removing the system.

And then China got issue of competent people monopolized for doing fast trading so it managed to pisv them to AI by forbidding fast trading. This made these expert work in ai field and they are now removing us competitive advantage buy open sourcing models. And us European are being depassed. Capitalisme killed innovation.

How can they suck that bad? A 29€ raspberry pi with a basic ML model can get 90% accurate results

I guess that they are implementing crappy cameras? Not sure about american plates, but in most jurisdictions licence plates are optimized for easy OCR:

Note how each letter is unique and can't be transformed with a sharpie into another. That also makes OCR easy. If you use a crappy dashcam, you will get problems regardless. Esp. in low light situations at higher speeds.

So I would guess that Flock uses cheap sensors and cheap lenses. Which kind of makes sense when they are putting out thousands of scanners.

[–] XLE@piefed.social 2 points 1 hour ago

In some cases in the US, cops enter both O and 0 into the search databases. This probably compounds the number of false positives.

Are they? Off the top of my head Germany is the only country I can think of that uses such a font (FE-Schrift).

[–] JensSpahnpasta@feddit.org 3 points 2 hours ago (1 children)

German wiki mentiones 42 countries that also adapted the FE Schrift and 7 that use some adaptions:

[–] lemmyvore@feddit.nl 1 points 2 hours ago

I see. I'm in Europe and it's not very common there so that's why.

[–] eager_eagle@lemmy.world 1 points 2 hours ago

in my area I struggle to distinguish D, O, and 0. Idk if someone was paid to design that, but they did an awful job

[–] HugeNerd@lemmy.ca 2 points 3 hours ago

Never seen letters like that on license plates in Quebec.

[–] swicano@programming.dev 29 points 5 hours ago

That's probably exactly what they did, deployed a sbc + some off the shelf model and increased the price 300x by making a black plastic shell.

[–] leriotdelac@lemmy.zip 5 points 3 hours ago

Yay! Great investment. Totally worth the buck.

[–] randompasta@lemmy.today 21 points 5 hours ago (2 children)

On one hand that's a good thing.

[–] ItsNotImportant24@lemmy.ml 14 points 4 hours ago (2 children)

But on the other its not, as it can cause someone else with a similar plate number to be accused of a crime or infraction, etc that another committed.

[–] XLE@piefed.social 4 points 3 hours ago* (last edited 1 hour ago) (1 children)

Dozens of times so far. And the perpetrators point at each other, or simply refuse to acknowledge wrongdoing.

Edit: found the story I was thinking of! This guy was wrongfully added to these lists, and the sheriff only removed him locally after the news stated investigating. And that's only for one county, so the problem will repeat if he drives to a different county.

[–] ItsNotImportant24@lemmy.ml 2 points 2 hours ago* (last edited 2 hours ago)

Yep, I knew it was happening. Wasn't aware this frequently already. Of course they point the finger at each other and refuse any wrongdoing, their lives aren't the ones at stake when shit like that happens. And guarantee the ones falsely accused still face the penalties.

[–] Catoblepas@lemmy.blahaj.zone 12 points 4 hours ago (1 children)

Yup, just read an article about that the other day. They even acknowledged it was going to keep happening to the person whose vehicle was mistakenly flagged because of a partial ID match, and just advised him to keep the car at home until they figured out how to fix it. In his case it wasn't as big a deal since it was a rental, but can you imagine being told to not drive your own fucking car or the cops will be automatically called to come pull you over as a carjacker??

[–] ItsNotImportant24@lemmy.ml 5 points 4 hours ago

Wow, that is absolutely insane. I hate this current timeline so much.

[–] cavitationfetishist01@quokk.au 6 points 4 hours ago

No. Its like drug dogs. Its just an excuse to do whatever they want. Infinite monkeys writing up probable cause forms.

[–] Catoblepas@lemmy.blahaj.zone 3 points 5 hours ago

I'm pretty sure I could do better stoned. I mean, I'm typing with a much higher accuracy than 71%, and I'm stoned right now.

[–] bad1080@piefed.social 2 points 4 hours ago

and how many false positives in the other 29%?

[–] cavitationfetishist01@quokk.au 1 points 4 hours ago* (last edited 4 hours ago) (1 children)

For context: I once lived in roseville and worked in Sacramento. They shared radio and otaTV stations back when those were a thing. I have heard about (insane) people commuting to sf from there.

This isn't bumfuck nowhere.

Side note: There's still over the air television, it's just digital instead of analog.
