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.
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 could see having a cop and a camera stationed in a place working as a spotter that then radios to other cops up ahead to pull over in an old school speed trap set up. However, that would take a lot of man power and coordination that I doubt most departments would care to do. We've seen plenty of YT videos of people trying to make a point of catching distracted drivers. The cops just need to give a shit, and want to do something about it.
