Containment Protocols
As of the publication of this article, the lethal properties of RPC-XXX-1 have been neutralized.
I'd change it to something like: "As of [DATE], RPC-XXX-1's lethal properties have been neutralized." If not, you should change "article" for "file" or "document"
The lingering eccentric qualities of RPC-XXX are mundane enough without RPC-XXX-1 that researchers believe they do not threaten public normality.
"eccentric qualities"?
I'd reword it to something like "As a result, RPC-XXX's persistent properties have been deemed mundane enough as to not pose a threat to normalcy"
[…] with fictitious ghost tales. Typically involving late-night encounters, these tales […]
I'd replace the first period with a comma and the first comma with a period.
Description
RPC-XXX is a random phenomenon in the State of California.
This tells me absolutely nothing, it's the same as saying "RPC-XXX is an anomaly" + you shouldn't capitalize "state" + it'd be better if you said "in [city/area], California, USA."
The entrance manifests as an offramp on Highways or roads adjacent to the Pacific Ocean.
Entrance to where? Again, you said basically nothing on the first sentence, so talking about an entrance just comes out of nowhere. Also, you shouldn't capitalize "highways"
And wouldn't this also mean that the anomaly can manifest anywhere in the west coast, and not just California? You're giving conflicting statements
specific environmental factors and personal choices
change to "specific individual and environmental factors"
surfboard or surfing paraphernalia
In such cases, it's better to say "and/or" unless it is specifically an either-or situation. This applies to all subsequent uses of "or" in this table
Night (Sun Down)
So, is it night or sun down? Those are two different times of day
without a map (GPS)
Same thing. A map and a GPS are too different things.
Also, what are those percentages based on? To what do chance do they add up to? Is it really random if you can increase/decrease the likelihood of it occurring? How much do they really matter? Are they additive or multiplicative? What is the base chance of this happening? 15%? 20%? 0.23%? Where did they get such precise percentages?
I feel it'd be better if you just turned it into a list of things that make it "more likely" to occur instead of trying to quantify it without a baseline.
During the RPC-XXX event
It's an event now? What is it, exactly? A static entrance? An event with a beginning and end? A general phenomena? How does this broken down car relate to the "entrance"? At no point yet have you mentioned the subjects needing to enter any entrance or encountering it. It's like -1 is a completely different anomaly.
as a ghostly but material apparition
"ghostly" is a highly informal term and directly conflicts with "material". It can't be fully material and fully immaterial at the same time
If the driver can not outrun
change to "If the drives fails to outrun"
they will be knocked off the road and into the sea rocks below.
Is this 100% guaranteed? Does -1 always get the car to flip off the road in a single hit? Does it matter if it's a ford fiesta 2011 or a large shipping truck?
During the Authorty's encounters with the anomalous vehicle, it was evident that it did not operate off traditional physics. For instance, the direction of speed is not a constant factor within RPC-XXX-1's frame of movement. Instead, the anomaly follows a continuous force of acceleration. If it were not for the forces of air and road friction, RPC-XXX-1 could reach speeds exceeding the sound barrier.
This feels like a lot of text just to say it is anomalously fast
Overall, the description felt all over the place. I'd recommend remaking it.
Discovery
only to black out and wake up in their car
Is this supposed to have been included in the description?
Site-95
All mentions of Site-95 should be changed to Site-095

change to "found shortly after beached"
body would never be found
why are you speaking in future tense? it should be "were never found"
Initially, Site staff
"site" shouldn't be capitalized unless you're writing the numeric designation of a site, like Site-095

Addendums
after Agent's death
after whose death?
RPC Researchers encountered RPC-XXX-1 fifteen times utilizing methods that increased the likelihood of an encounter.
Simply say "Researchers encountered", there's not need to specify "RPC", and even if you did need to specify, the term used would be "Authority". Also, why did they send out researchers out for dangerous field work?
In all cases where RPC-XXX-1 was challenged, Researchers would be run off the road.
Again, why did they send researchers out on possibly-lethal tests when you have a whole class of tests subjects for these exact scenarios? Or hell, at least send Containment or Protection personnel, someone who's a bit more versed in field work and dangerous situations.
ss if it's waiting

The letter is cute, but what does it have to do with a killer car that goes on about and kills random couples and surfers
confirmed that RPC-XXX-1 was a spiritual or infoplane apparition tied to the material plane
How is a physical car in any way, shape, or form, coming from the infoplane? And "spiritual apparition" is both informal and incredibly vague that you might've as well just said "ghost"
would sever RPC-XXX-1 from this world forever
Highly informal

gassed up?
Final Thoughts
This article was all over the place. The description barely described what the anomaly WAS for the first half of it. Hell, even after it was done I still have no idea what exactly the "entrance" is, or how it still exists since the only way (afaik) to tell you're in it is RPC-XXX-1 itself.
There's an abysmal conflict between the loving, mournful tone of the letter/poem and the actions of RPC-XXX-1, so it ends up feeling a bit pointless to have it, as is the whole ritual around the car. Also, why would RPC-XXX still exists once RPC-XXX-1 is gone? Was RPC-XXX just a random, unrelated road anomaly and not something associated with the car ritual thing?
I feel you should try to lean more heavily into the narrative you set up with the poem or at least make something that makes a bit more sense to go along with a murder car. That is besides remaking the description to make sense, of course.
