Cueball explains being worried about self-driving cars, noting that it may be possible to fool the sensory systems of the vehicles. This is a common concern with AIs; since they think analytically and have little to no capability for abstract thought, they can be fooled by things a human would immediately realize is deceptive.
However, Cueball quickly assumes that his argument actually doesn't hold up when comparing AI drivers to human drivers, as both rely on the same guidance framework. Human drivers follow signs and road markings, and must obey the laws of the road just as an AI must. Therefore, an attack on the road infrastructure could impact both AIs and humans. However, humans and AIs are not equally vulnerable. For example, a fake sign or a fake child could appear to a human as an obvious fake but fool an AI. A creative attacker could put up a sign with CAPTCHA-like text that would be readable by humans but not by an AI.
Cueball further wonders why, in this case, nobody tries to fool human drivers as they might try to fool an AI, but White Hat and Megan point out the most obvious answer: most road safety systems benefit from humans not actively trying to maliciously sabotage them simply to cause accidents.
The title text continues the line of reasoning, noting that if most people did suddenly become murderers, the AI might be needed to be upgraded in order to deal with the presumable increase in people trying to cause car crashes by fooling the AI - a somewhat narrowly-focused solution given that a world full of murderers would probably have many more problems than that. As Megan sees humans as a 'component' of the road safety system, it might also be suggesting a firmware update for the buggy people who have all become murderers, one that would fix their murderous ways. We are not currently at a point where we can create and apply instantaneous firmware updates for large populations; even combining all the behavioral modification tools at our disposal -- psychiatry, cognitive behavioral therapy, hypnosis, mind-altering drugs, prison, CRISPR, etc. -- is not enough to perform such a massive undertaking, as far as we know. The update might be about the car's firmware since it can used to disable the breaks and thus causing or preventing many deaths.
- [Cueball is speaking while standing alone in a slim panel.]
- Cueball: I worry about self-driving car safety features.
- [In a frame-less panel it turns out that Cueball is standing between White Hat and Megan, holding his arms out towards each of them, while he continues to speak.]
- Cueball: What's to stop someone from painting fake lines on the road, or dropping a cutout of a pedestrian onto a highway, to make cars swerve and crash?
- [Zoom in on Cueball's head as he continues to contemplate the situation holding a hand to his chin, while looking in White Hat's direction. Megan replies from off-panel behind him.]
- Cueball: Except... those things would also work on human drivers. What's stopping people now?
- Megan (off-panel): Yeah, causing car crashes isn't hard.
- [Zoom back out to show all three of them again.]
- White Hat: I guess it's just that most people aren't murderers?
- Cueball: Oh, right. I always forget.
- Megan: An underappreciated component of our road safety system.
The title text was published with a typo: "murderers" was misspelled as "muderers."
The theme of human fear and overreaction to the advent of more or less autonomous robots also features in 1955: Robots.
Self-driving cars is a recurring subject on xkcd.
A variation on the idea that humans are mentally "buggy" is suggested in 258: Conspiracy Theories, though in that case divine intervention is requested to implement the "firmware upgrade".
This comic appeared one day after the Electronic Frontier Foundation co-released a report titled The Malicious Use of Artificial Intelligence: Forecasting, Prevention, and Mitigation. The report cites subversions and mitigations of AI such as ones used in self-driving cars. However, the report tends toward overly technical means of subversion. Randall spoofs the tenor of the report through his mundane subversions and over-the-top mitigations.

I assume the off-panel speaker is Megan, based on their positioning, but not sure what the ruling on the ambiguity is. PvOberstein (talk) 05:47, 21 February 2018 (UTC)
I made a note about the typo in the title text. Also, weird question, does the "created by a BOT" tag mean that the explanation was written by an AI? Or is it a joke I'm missing for some reason? Sorry, kind of a dumb question I guess. 09:04, 21 February 2018 (UTC)
- Afaik the "created by a BOT" part is the default text when the bot which is crawling xkcd for a new comic inserts the comic here (and an empty explanation). In the past that part was often deleted when the first real edit was made. Some comics ago a habit evolved to actually change that line in relation to the comic at hand (e.g. "created by a SELF-DRIVING CAR" would be fitting here).

- Oh, okay...19:06, 21 February 2018 (UTC)
- It refers to the incomplete tag. The incomplete tag is created by a bot and just shows that there needs to be an explaination. Lupo (talk) 19:09, 25 February 2018 (UTC)
Could the firmware update be for the humans, because they are obviously malfunctioning in the scenario? Sebastian --184.108.40.206 09:46, 21 February 2018 (UTC)
- Of course, that's the joke. It would be really impractical to install such a firmware update, there are about 7.5 billion people on earth - many of which we don't even have access to. I'd also suspect that most people would fight back if you tried shoving a USB flash drive into them. 220.127.116.11 11:24, 21 February 2018 (UTC)
- Yeah, but how many of those 7.5 billion people are a safety risk for self-driving cars, though? LordHorst (talk) 12:59, 21 February 2018 (UTC)
- My best guess is 12. 18.104.22.168 14:50, 21 February 2018 (UTC)
- Huh, I never even realized this interpretation. :) Hawthorn (talk) 15:09, 21 February 2018 (UTC)
- But you wouldn't use a flash drvie - it would be an OTA update.22.214.171.124 11:53, 22 February 2018 (UTC)
- Funny, but now, as the explanation now states it is the cars that need to be updated to take this new behavior in to context. It is unclear if the cars should behave like humans, as Cueball mentions they already do, and if so should try to use the knowledge of human behavior to save life, or if they should behave like humans and try to take lives! :-D --Kynde (talk) 13:14, 21 February 2018 (UTC)
- While this version occurred to me, I feel confident that the INTENDED meaning is to go within the context of this comic, that is, that the murderers are the non-drivers Cueball is afraid of, and both human and AI drivers alike still would prefer not to crash (especially seeing as the most available murder victims would be the people in the car, both passengers and possible driver). Still, the car-owners-want-to-kill version is amusing. LOL! NiceGuy1 (talk) 05:33, 23 February 2018 (UTC)
- To me it's obvious, and the explanation overthinks it. The natural "voice" of the comic here is Cueball. He surmises that if people generally become murderers, they would need a firmware update "or something". Obviously he is taking "people" to be some sort of product, and the update to be the manufacturer's obligation. There is obvious religious precedent for this, whether the "firmware update" involves unleashing floods, burning cities with fire, sending messaiahs or revealing truths to prophets... and that is (imho) the joke: Cueball thinks an update is needed, then he generalises that to "or something" as he starts to realise (or as the reader starts to realise, despite Cueball's obliviousness) the enormity of the consequences of such a possible update. 126.96.36.199 03:42, 3 March 2018 (UTC)
- Agree with the interpretation, but I think floods, fire, etc. would be more 'retiring hardware' than a 'firmware update' 188.8.131.52 09:28, 5 March 2018 (UTC)
I would say that it's easier to fool current AI than human ... except in "quick reaction needed" scenario. If you throw cardboard cutout of a pedestrian on road, AI will be fooled because it's not able to recognize it's not human and crash. Human will crash as well, because while he will eventually realize it's cutout, it would be too late. -- Hkmaly (talk) 23:35, 21 February 2018 (UTC)
A creative attacker could put up a sign with CAPTCHA-like text that would be readable by humans but not by an AI.
Except that both humans and AIs would disregard it as not being a real sign. In fact, this would be more likely to be successful as an attack against humans, who might at least be distracted by going "what's that?", and end up crashing as a result. The AI would just completely ignore it.184.108.40.206 11:56, 22 February 2018 (UTC)
One of the most ingrained features in humans is to always drive on the correct side of the road
Seems like rather a big claim there... 220.127.116.11 15:03, 22 February 2018 (UTC)
It still says "muderers"[sic] ... maybe it isn't just a misspelling? 18.104.22.168 22:59, 11 March 2018 (UTC)
