Built this over the last few days, based on a Rust codebase that parses the latest ALPR reports from OpenStreetMaps, calculates navigation statistics from every tagged residential building to nearby amenities, and tests each route for intersection with those ALPR cameras (Flock being the most widespread).

These have gotten more controversial in recent months, due to their indiscriminate large scale data collection, with 404 Media publishing many original pieces (https://www.404media.co/tag/flock/) about their adoption and (ab)use across the country. I wanted to use open source datasets to track the rapid expansion, especially per-county, as this data can be crucial for 'deflock' movements to petition counties and city governments to ban and remove them.

In some counties, the tracking becomes so widespread that most people can't go anywhere without being photographed. This includes possibly sensitive areas, like places of worship and medical facilities.

The argument for their legality rests upon the notion that these cameras are equivalent to 'mere observation', but the enormous scope and data sharing agreements in place to share and access millions of records without warrants blurs the lines of the fourth amendment.

I've thought about this a lot as I see more and more reckless driving in the areas I live in. Surveillance is generally a net negative, but it's also bad when you see people speeding around schools, rolling through stop signs, and running red lights. We seem to have a worst of all situations where traffic is getting increasingly difficult to enforce, driving is getting more dangerous year by year, and we're terrified of government overreach if we add any automation at all to enforcement.

I don't know the solution, but I do know that in the US we've lost 10-15 years of progress when it comes to traffic fatalities.

Part of the public pushback is that people almost always drive the “feels like” speed and not the posted speedlimit. We build 6 lane roads and then wonder why people go 50mph when it’s 35 posted, it’s because it’s 6 lanes and 35 feels slow. Cities profit from this in the form of speed cameras, which is why they’ve been outlawed in a lot of places.

If the speeds aren’t appropriate for the built environment, then the limits should be changed or the environment should be changed. Enforcement of the law should be consistent regardless of the quality of the law.

The speeds are appropriate for the roads generally. I mean, at the lowest level speed limits are a matter of social consensus so the broad public is tautologically correct.

The problem is that knocking the magic number on the sign down by 5-15 and then simply not enforcing it too seriously results in less screeching Karens harassing the politicians who then harass the bureaucracy than taking a hard line about "well akshually this is the engineered speed for the road".
