These are two very different metrics and I'd be interested to see what a proper comparison actually looks like here. As it's currently presented, this feels kind of dishonest.
Rather than comparing the citations from speed cameras with the totality of all traffic stops made by police, a more honest comparison would be the racial distributions for speeding tickets given by police vs speed cameras.

That one's particularly interesting because it had a rock-solid natural control; they looked at incidents one week before daylight savings through one week after. They saw an instant one-hour shift in police traffic stop patterns that quite simply cannot be explained away as "well black people drive worse".

That's not what they did; they only counted speed citations in the study.

Okay so I found the paper and read through it to see if it said something contrary to what the article written by the researchers themselves said and you seem to be incorrect. The study is very clearly just traffic stops in total, not speeding tickets. In fact it's not even that, but a complex model estimating the traffic stop distribution.
Based on the study text, I'm guessing the data they need for this is simply unavailable so this is the best they could do, which I find both surprising and unfortunate. I personally think it would be worth collecting this kind of data precisely so that more robust arguments can be made.

While an unbiased enforcement system is naturally a good thing, I can't help but wonder what strategies the middlemen who build these systems use to get public support. Consider this, what if these systems are built in a predatory manner, positioned at locations where a speed limit change is non-obvious, or at intersections where the timing of yellow lights is reduced below the usual? If a portion of everyone on the road is getting ticketed, then of course it would appear "unbiased". While I can't speak to the nature of these cameras, a misleading studying directly advocating for more of these systems should always raise alarms unless they have good data backing them.
So in summary, not only have you misrepresented my complaint with your strawman: "well black people drive worse" argument, you yourself were dishonest about the contents of the study you clearly did not read.
I don't think I will be replying to any other posts in this thread since this overall discussion has been unproductive and frankly a waste of my time.
> Overall, while the proportion of tickets going to Black and White drivers is close to their roadway share, based on the relative citation rate discussed in the prior paragraph, we find that speed citations are higher for Black drivers than White drivers after controlling for the roadway composition.
Do go off, though.

I will point out to anyone else bored enough to read this silly comment chain that they quoted the section from "Camera Enforcement and Racial Composition", not the section about police stops and the amount of citations that come from them. Even in the main article you can see that the tentatively "unbiased" speed cameras ticketed black people slightly more than everyone else by a negligible amount (~4%).
Ironically the entire premise of the article was that speed camera citations are unbiased so this quote is kind of, what do you even call this? Since this was taken out of context to misrepresent the implication, lets just leave it at deliberate misinformation, since I simply can't understand how someone could do this accidentally. Maybe they wanted to take advantage of the fact I said I was unlikely to reply? Who knows?
“Our findings show that when speed cameras are doing the ticketing, the proportion of tickets issued to Black and white drivers aligns closely with their respective share of roadway users. With human enforcement, in contrast, police officers stop Black drivers at a rate that far outstrips their presence on the road.”
The rate that speeding tickets are issued when police are involved rather than automation is very clearly racially biased.
First it's not what GP said at all... But seen that you obviously want to go down that route here's a harsh reality check which you're not going to like.
Here are official numbers from the FBI from 2018, only concerning white and black victims and white and black murderers:
3114 murders of either black or white (but mostly black) victims by black perpetrators
2911 murders of either black or white (but mostly white) victims by white perpetrators
But then in 2018 black people only made about 13% of the US population while non-latino whites made about 61% of the population.
Invoke socio-economic status / class warfare or whatever you want to explain why black people are 5x more likely to commit murder but the official numbers are there and hard to dispute.
FWIW my family is white, black and yellow so you can safely send your "racist" card to /dev/null.

Excuse me? This is an extremely uncharitable interpretation of my reply.
> “Our findings show that when speed cameras are doing the ticketing, the proportion of tickets issued to Black and white drivers aligns closely with their respective share of roadway users. *With human enforcement, in contrast, police officers stop Black drivers at a rate that far outstrips their presence on the road.*”
This is precisely the text that lead to my reply, why would they compare speeding tickets from speeding cameras with traffic stops by police and not speeding tickets from police? I'm not denying there is something here, just that this is a dishonest comparison.
In fact if you had read to the end of the article you would have seen they even indirectly allude to this:
> Over half of police stops in Chicago for 2023 were license plate, registration or equipment related. Automating enforcement of such nonmoving violations would eliminate a major reason for police-driver interaction, reducing the potential for bias and escalation.
