Special Containment Procedures: Total containment for 
SCP-3525 has not yet been achieved; accordingly, these 
procedures are still being developed and are subject to further 
modification as more information is gathered. 


Foundation technicians have installed backdoors in all major 
rideshare application servers allowing them to intercept any ride 
pickup confirmations from perfectly-rated drivers who do not appear 
in those applications’ servers. These drivers should be re-routed to 
available Foundation personnel for testing purposes if available and 
otherwise simply canceled. The same safeguards should be 
installed in any new rideshare applications developed, although 
where possible their parent companies should be acquired and shut 
down in order to avoid spreading Foundation technical resources too 
thinly. 


D-class personnel assigned to test SCP-3525 should be fitted with 
standard exploding-bolt collars and tracking devices to ensure they 
do not avoid re-containment after their ride completes. 


Description: SCP-3525 is an anomalous phenomenon linked to all 
major rideshare applications! that manifests when the app assigns a 
driver with a perfect 5-star rating to pick up a rider. Upon entering 
into these drivers' cars, riders uniformly report a sense of vague 
unease without being able to pinpoint the cause. After a few 
minutes, the driver then asks the rider a number of personal 
questions, starting from innocuous questions about personal well- 
being and progressing to interrogating them about their secrets, 
desires, and fears alongside detailed questions about their home 
lives and work responsibilities. Riders report a growing certainty that 
the driver will cause them physical harm if they refuse to answer 


these questions, although this does not appear to be a strict 
compulsion effect and riders can choose not to answer. In no case 
thus far has an SCP-3525 driver caused physical harm to any rider. 


While in the car, riders describe the scenery as becoming surreal 
and unfamiliar. Common descriptions include buildings bending at 
alien angles, people outside becoming blurry and indistinguishable, 
and all physical landmarks disappearing entirely. However, external 
monitoring only shows the car moving along the most efficient route 
to its destination. Ridesharing carpools affected by SCP-3525 
terminate in one of two ways: either the driver successfully delivers 
the rider to their intended destination or they stop at a midway point 
and ask the rider to leave, refusing to keep driving until the rider 
exits. Riders who successfully reach their intended destination have 
been observed to exhibit erratic behavior following their exposure to 
SCP-3525, including memory loss, personality shifts, and general 
confusion. Riders who stop short of their destination do not display 
these symptoms. Riders additionally report that the time spent in the 
car feels significantly longer than the apparent elapsed time; this 
temporal discrepancy has been confirmed via testing (see test log 
below). 


No information about SCP-3525 drivers can be found in the 
databases of the apps in question and the mechanism by which they 
are assigned is currently unknown. In addition, they share no 
apparent commonalities apart from their 5-star rating, varying on 
race, gender, age, appearance, and make and model of car; 
similarly, the riders who get these drivers appear to be randomly- 
selected. SCP-3525 cars additionally appear to block all 
transmissions; GPS signals, telephonic communication, and radio 
contact all cease the moment a rider steps into the car and closes 
the door, although they do resume once the car door is opened 
again. 


While many of the SCP-3525 riders contacted the app companies to 
complain, these complaints appear to have largely been ignored. 
Accordingly, the Foundation only became aware of the phenomenon 
several years after it had been in effect when a Foundation agent 
happened to experience an SCP-3525 manifestation firsthand as a 
rider, at which point the anomaly was reported, verified, and 


contained. 
Addendum 3525-a: Partial Test Log 


Note: Given the wide geological range of this phenomenon and the 
sudden nature of its manifestation, many of these tests were 
performed in a somewhat ad-hoc manner, taking advantage of 
whatever D-class personnel that were at hand and with test plans 
invented on the spot. Dedicated testing protocols are still a work in 
progress. 


Show Experiment Log 


Experiment 3525-1 

Location: Seattle, USA 

Procedure: Control experiment; subject was 
given no special instructions. A D-class with 
limited exposure to Foundation assets was 
chosen to minimize information leakage. 
Subject was fitted with audiovisual recording 
device and remote broadcasting device. 
Results: Subject was successfully transported 
to intended destination. While the outside time 
elapsed between source and destination was 
only 15 minutes, the recorder picked up an 
interrogation lasting approximately 4 hours that 
touched on all aspects of the subject's life to 
date, including his day-to-day life as a 
Foundation asset and his previous arrest for 
[REDACTED]. The visual recordings 
additionally confirmed that the view from inside 
the car's windows was at odds with its physical 
location and displayed scenery that bore no 
resemblance to the actual outside. The remote 
broadcasting device was rendered inoperable 
for the duration of the ride. After the test 
concluded, the subject was quarantined and 
observed; subject displayed an increased 
tendency to focus on his previous crimes and 
some apparent memory loss. 


Experiment 3525-2 

Location: San Francisco, USA 

Procedure: Multiple Foundation vehicles 
blocked the driver in when he arrived for 
pickup, with orders to extract and contain the 
driver. 

Results: When the driver realized he was 
unable to leave, he immediately self- 
terminated by forcibly ripping his throat out 
with his fingernails, severing his carotid artery. 
An autopsy revealed no anomalous 
physiology. The frequency of SCP-3525 
manifestations was not impacted in any 
noticeable way by the death of this driver. 


Experiment 3525-4 

Location: Paris, France 

Procedure: Experiment 3525-2 was repeated, 
but this time the blockade happened midway 
through the ride. D-class subject instructed to 
attempt to drive the car if driver self- 
terminated. 

Results: Driver self-terminated as before upon 
being impeded. The subject was unable to 
drive the car at this point, although she 
continued to record anomalous visual footage. 
After she opened a door, all anomalous visual 
footage immediately stopped and the car 
became drivable again. 


Experiment 3525-7 

Location: Shanghai, China 

Procedure: Control experiment repeated; 
procedure exactly the same as Experiment 
3525-1. 

Results: Driver stopped midway. Recording 
indicates that this occurred after the subject 
was interrogated about the Foundation at 
length; no classified information was disclosed 
and no more detail was presented than in the 


first control experiment. Subject placed under 
quarantine but has thus far not displayed any 
erratic behavior. 


Experiment 3525-12 

Location: Jakarta, Indonesia 

Procedure: Subject was provided with a 
syringe containing a calibrated dose of sodium 
thiopental and instructed to inject the driver 
during the ride. Foundation personnel would 
then extract and contain the driver. 

Results: Subject was able to successfully 
administer the anesthetic; driver attempted to 
self-terminate but was rendered unconscious. 
Driver was extracted and contained at Site-44. 
Upon regaining consciousness, the driver 
lapsed into a semi-catatonic state; while she 
maintained respiratory activity, she remained 
unresponsive to all outside stimuli. MRI scans 
revealed minimal brain activity but no 
anomalous neurology. 


Experiment 3525-16 

Location: Boston, USA 

Procedure: Control experiment performed for 
third time. 

Results: Same as Experiment 3525-7. 


Experiment 3525-23 

Location: Mexico City, Mexico 

Procedure: Control experiment performed for 
tenth time. 

Results: Same as previous eight experiments. 
The only recorded experimental instance thus 
far of the rider successfully making it to their 
destination is Experiment 3525-1. 

Followup: A re-analysis of riders subjected to 
SCP-3525 prior to Foundation containment 
revealed that those who made it to their 
destination are uniformly distinct from one 


another. That is, once a rider makes it to their 
destination, any subsequent rider with the 
same socioeconomic background and 
profession will invariably stop short. 


Experiment 3525-37 

Location: San Francisco, USA 

Procedure: For several weeks a D-class 
subject was conditioned to respond to all 
personal questions as though he was a 
Foundation agent; a thorough fictional 
backstory was constructed, intended to cover 
all aspects of interrogation. No amnestics were 
applied and the conditioning was entirely 
psychological in nature. As with all previous 
tests, an audiovisual recorder was supplied. 
Results: Subject was successfully delivered to 
his destination. Upon recovery, the subject 
continued to act as though he believed his 
fictional backstory even after multiple rounds 
of deprogramming. Subject additionally 
appeared not to recognize Foundation staff he 
had interacted with repeatedly, other D-class 
subjects he had previously been acquainted 
with, or photographs of his family members. 
Finally, the subject appeared to be equally 
unaware of certain aspects of his own fictional 
backstory; analysis of the ride recordings 
revealed that the only aspects he has 
maintained the veracity of were those that he 
was explicitly interrogated about during the 
SCP-3525 manifestation. 


Experiment 3525-51 

Location: San Francisco, USA 

Procedure: Same subject from Experiment 
3525-37 was assigned to be a rider. Subject 
continues to maintain his fictional backstory. 
Results: The driver remained entirely silent for 
the duration of the ride and the elapsed time 


inside the car was precisely identical to the 
elapsed time outside. This is the first time 
either of these results has been recorded. 


Experiment 3525-78 

Location: London, UK 

Procedure: Three subjects assigned to ride 
together. 

Results: As with Experiment 3525-55, the 
driver first started interrogating one subject, 
picked apparently at random. However, exactly 
2 hours and 14 minutes into this interrogation 
(elapsed time outside: 7 minutes), one of the 
indistinct pedestrians visible through the car 
windows on the recording rushed up to the car 
and physically slammed into it. The driver 
immediately sped up and drove silently for a 
full hour (elapsed time outside: 1 minute) 
before stopping and instructing all riders to 
leave. 

Followup: All further subjects are to be 
provided with a dose of sodium thiopental and 
instructed that if one of the pedestrians visible 
via the car windows attempts to interact with 
the car, they are to immediately inject the 
driver and attempt to communicate with the 
pedestrian in question. 


Addendum 3525-b: Transcript of audio recording, Experiment 


Note: The following is a transcript of the second encounter with a 
pedestrian during an SCP-3525 manifestation. For the purposes of 
this transcript the driver is referred to as SCP-3525-1, the pedestrian 
as SCP-3525-2, and the rider by his designation, D-17214.

[Three hours of non-pertinent dialog omitted.] 


SCP-3525-1: ...when did you drop out of 


HQ: Understood T3L. Keep going. 


T3L: So the rest of the squad, we go back down the 
stairs, can't go up, not going in that hallway. All the rest 
of the floors were closed off. We went down maybe... ten 
more flights... Then the stairs started changing. They 
were solid metal, like aluminum but now there were 
holes in the steps, and the metal looked rusted in some 
places, old. Like the rest of the ship. Up until now 
everything had seemed rather clean, it didn't dawn on 
me immediately that the clean parts were actually 
stranger than the old parts... 


T3L: We found a food storage area down here, 
everything seems in good shape, but we didn't touch any 
of it yet... | read the Team 2 logs. | sent a man out into 
the hall to see what we could do on this floor. There 
seems to be a series of ladders in a group at the far end, 
but the entirety of this floor is food storage... it actually 
doesn't make sense why there are so many of these 
rooms. I'm talking over twenty on this one floor, and 
they're all big enough for ten people to stand inside and 
have room to move. Some of them are locked... 
probably for the best. 


HQ: And the ladders? 


T3L: We haven't gone down them yet. Wanted to see if 
we could get someone from the outside first. 


HQ: DOWN? They go DOWN? What the flaming shit is 
going... okay... sweet Dapper Jesus of the Gentlemen's 
Club. Look, | don't want to put any of you at risk, but we 
need to find you a way out of there. If you can't go back 
up, and you can only go down, only send one man. T3V 
and Evans are topside and perfectly fine. We're sending 
a diving crew around the ship exterior to see if we can 
pinpoint your location inside it using thermal. 


T3L: Understood sir. 


school, [REDACTED], and what drove that 
decis- 


At this point a loud impact can be heard; the 
camera (mounted on D-17214's head) swivels 
to catch SCP-3525-2 pressed against the car 
window. 


D-17214: Oh... oh, right, okay, here we go- 


A flurry of movement occurs. Followup 
investigation revealed that D-17214 missed 
the injection point (inserting the syringe into 
SCP-3525-1's shoulder instead) and 
SCP-3525-1 managed to self-terminate. 


D-17214: Whoa. [laughter] Man, that's messed 
up. Guess he just wasn't into needles, huh? 
[laughter] You, uh, you saw that he did that to 
himself, right? | had nothing to do with it, just 
want to make that clear. Annoying prick, 
though. 


D-17214: Okay, now where's that other guy 
gone off to? 


The camera swivels to the back window. 
SCP-3525-2 is still visible, although several 
dozen feet away now. After a short pause, it 
begins to walk towards the car, eventually 
pressing its face up to the window again. From 
up close, SCP-3525-2's features appear to 
shift repeatedly in size and shape every few 
seconds, as though being refracted through a 
number of lenses in rapid succession. 


D-17214: You're... real hard to look at, buddy. 


There is no response. D-17214 pulls out a 
Foundation-written questionnaire. 


D-17214: So much for small talk. Okay, uh... 
who are you, and what is your purpose here? 


SCP-3525-2's mouth moves slowly but no 
sound is audible. 


D-17214: Hey, do you hear me? Who are you? 
Do you have a name? 


SCP-3525-2: (quietly) Two-eight-four two- 
three-three two-seven-eight two-five-oh two-fo- 


D-17214: Is that... what is that? Is that your 
name? 


SCP-3525-2: (louder) Name... name. Name. 
Name? 


D-17214: Yeah, dummy, name. Like, my name 
is [REDACTED], and your name is...? 


SCP-3525-2: Name. Name is Carl... no, 
Carlton? Carlton. 


D-17214: Huh. Surprisingly normal, for a 
creepy jello-faced guy. All right, Carlton, what's 
your purpose here? What are you doing here, 
exactly? 


SCP-3525-2: Don't... know. 


D-17214: Okay, well, they didn't give me a lot 
of instructions about followup questions, so I'm 
just going to take that one at face value. 
Moving on: What is this place, and where is it? 


SCP-3525-2: Nothing. 


D-17214: So... is that an answer to both 
questions, or- 


SCP-3525-2: It is a lack. It stretches on without 


end or meaning. The buildings are shells, 
empty. Dewey stole eight bags. No one 
speaks, or hears, or knows. It's a place to lose 
yourself, softly. Jerry scored eighty-seven.
