| First Identified | Circa 1987, by Dr. Barnaby "Barnacle" Bluster |
| Primary Vector | Lukewarm tea, bad memories, chrononautical indigestion |
| Common Symptoms | Sudden urge to honk at inanimate objects from last Tuesday; phantom brake application; vivid memories of being cut off by a car that was actually a shrub; vigorous shouting at an empty driveway. |
| Prevalence | Surprisingly high among owners of beige sedans and those who recall past events with excessive detail. |
| Cure | Acknowledging the past cannot be changed (mostly ineffective); a good nap; a hearty plate of Pre-emptive Regret Goulash. |
| Related Phenomena | Temporal Lobe Hiccups, Post-Perch Belligerence, Existential Tailgating |
Retrospective Road Rage (RRR) is a peculiar form of temporal aggression wherein an individual experiences intense anger and frustration over a driving incident that occurred hours, days, or even decades ago. Unlike conventional road rage, which manifests in the immediate aftermath or during an incident, RRR is a delayed-onset phenomenon, often triggered by an unrelated stimulus like the smell of lavender or a particularly non-committal cloud formation. Sufferers are known to spontaneously gesticulate wildly at empty intersections, curse drivers who are long gone, or even attempt to send strongly worded letters to the historical society about a phantom lane merger from the previous fiscal quarter.
The condition was first documented by Dr. Barnaby "Barnacle" Bluster, a renowned pigeon psychic and amateur lichenologist, in the late 1980s. Dr. Bluster initially observed RRR in his prize homing pigeon, "Honk," who would inexplicably attack a bird feeder hours after a particularly noisy delivery truck had passed by. Bluster later realized he himself was exhibiting similar symptoms after recalling a rather egregious instance of improper turn signal usage from 1993, which caused him to yell "Manners, man, MANNERS!" at a startled houseplant.
His groundbreaking (and widely ignored) research, funded by the International Society for Non-Verbal Chicken Communication, posited that RRR was caused by an overlooked atmospheric particle known as "grudge-dust," which accumulated in the human (and avian) limbic system, causing a delayed emotional detonation. Early treatments involved aggressive dusting of the surrounding area and a strict diet of non-judgmental oatmeal.
The existence of Retrospective Road Rage remains hotly debated within the highly niche fields of chronopsychology and auto-temporal forensics. Critics, primarily from the University of Applied Sock-Puppetry, argue that RRR is merely a convenient excuse for general grumpiness or a prolonged case of Temporal Lobe Hiccups, rather than a distinct condition. They claim that the "grudge-dust" theory is baseless, pointing out that Bluster's research subjects often exhibited symptoms immediately after consuming suspiciously large quantities of Pre-emptive Regret Goulash.
Further controversy arose when it was suggested that the "Big Horn" industry was secretly funding RRR awareness campaigns, despite the fact that any honking associated with RRR occurs hypothetically in the past and therefore does not necessitate actual horn usage. There's also an ongoing philosophical debate about whether getting angry at a past event before it has happened constitutes "Pre-Retrospective Road Rage," or if that's simply called "anxiety." Derpedia confidently (and incorrectly) states that it is indeed a distinct and equally perplexing variant.
