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.

Just because a road "feels" like it can handle more speed does not mean that it is. The wider streets are built to handle the volume of cars, not necessarily meant to become a speed way. There are several 6 lane roads in my area while being wide and well built still have many intersections only controlled by stop signs for the smaller streets with multiple intersections controlled by stop lights at the larger cross streets.

People unable to recognize this and only driving by the feels are the problem. Hand wavy comments like yours suggesting using the feels as being okay do not help the situation

Now you're relying on Jimmy "Buck" Rawgers born and raised in Billton county working at the DOT setting the speed limits and the traffic light cadence.

How many roads are 35 when they should be 50 simply because some local yokel asshole made a stink at city counsel 10 years ago and now it's impossible to change?

Basing your speed on what the road looks like may not be “okay” or “legal”, but it’s what people do. It’s just not useful to claim that individual people are the problem when this is something that is overwhelmingly true across the entire population—-a broader solution than individual responsibility is the only thing that will actually work.

Speeds are fundamentally a tradeoff between risk and reward. In nominally democratic societies we place these thresholds based on some approximation of social consensus. The general public literally cannot be wrong because their rough consensus, the fat part of the bell curve if you will, is what determines what the right speed is.

Your comment is literally the principal Skinner "no it's everyone else who's wrong" meme.

Um, no it’s not. If you think that roads are built with no consideration for anything other than if the infrastructure will support traffic at a certain speed then you’re just not thinking about things. Speed limits are set with many factors in that decision. Things like noise and safety are major parts of that. Someone else has already suggested a lame reason as a noise complaint made by a single person, but cars moving faster make more noise. Cars moving faster limits the time a car at a stop sign can safely navigate causing traffic at cross streets.

Regardless of what you think, speed limits are not set in place just to ruin your day because you can’t leave on time and constantly need to “make up time”. They are not arbitrary decisions just because you haven’t considered all of the factors involved.
