Forum user recalls the day a wheel overtook his car

When your memory is the only proof of what peine

Nobody remembers what peine. What we call memory is a reconstruction, and sometimes it is a one-person reconstruction: you swear you lived through a scene and the rest of the cast not only doesn't remember it, but denies ever having been in the casting. The question, raised in a forum, has gathered numerous replies. Not all of them are parallel-universe theories or conspiracies: workshop stories, school playground tales and neighbourhood anecdotes abound.

The most striking case, as told by the thread's author, has four wheels and a proud father. The son of an acquaintance starts working at a garage; the father goes in to have his tyres changed so the lad can look good in front of the boss. A few kilometres down the road, a freshly fitted wheel overtakes the car. It stops, he picks it up, puts it back on and drives on. Some time later he repeats the visit with another car, to give the boy a second chance, and exactly the same thing happens. Everyone present was in stitches as he told the story. Years later, nobody remembers a thing: neither those involved nor those who heard it.

Can a car keep rolling for a few metres after losing a wheel?

Yes, for a short stretch and in a straight line. That is the conclusion that gains ground when the story is put to kitchen-table physics. The most concrete account comes from someone who lived it: at around 40 km/h, with traffic all around, his front wheel on the driver's side came loose; the impact against the tarmac was hard, the car pulled to the left and ended up against the kerb. There was no spectacle, just a fright and a dented panel. The other objection is mechanical: the bolts don't stay hanging off the rim, and torque is checked with a torque wrench or, as the lesser evil, with an impact gun. Some add that a Citroën with hydropneumatic suspension could stay upright on three wheels. The anecdote is not proven. The lesson is: what sounds impossible is almost always just improbable.

The Fruit of the Loom Mandela effect: the cornucopia that never existed

We jump from individual to collective memory as soon as a brand appears. The well-known underwear brand with the cornucopia in its logo taught more than one person what a cornucopia actually was. Except that, so the claim goes, there never was a cornucopia. The rebuttal comes quickly and complicates the picture: anyone buying one of the brand's products today insists the horn is still printed there. The inventory of shared cracks keeps growing unchecked: the black-tailed Pikachu, the chewing gum that went into your stomach, the heart in the middle of the chest instead of the left side. And a dog, fox and raccoon hybrid of which, according to one forum user, only two real photos exist. The boring explanation — the company redesigns and nostalgia does the rest — doesn't convince everyone.

Induced false memories: they're manufactured over after-dinner conversation

You don't need an alternative universe to implant a scene. Suggestion is enough. One story tells how, at twenty, the writer would amuse himself dropping false statements with total confidence —I've heard that— and watching them take hold among those present. The mechanism has a domestic, everyday version: the classic gaslighting, in which a partner denies having said what they said until you doubt your own judgement. And an involuntary, more frequent version: in a primary school class there were two boys named Óscar and a teacher who handed out the odd clip round the ear; one of the two fainted on his own. Forty years later, an old classmate remembered a slap that had knocked the other Óscar to the ground. Nobody can prove anything. Imagination filled the gap and filed it as fact.

Parallel universes, timelines and a Denver airport

When neuroscience isn't enough, amateur physics steps in. Some describe these glitches as jumps between timelines: you remember what you lived in another universe, which is why those around you deny it. The brain would be a radio receiver that tunes in here today and there tomorrow. Hence the objects that evaporate — the favourite toy, the tongs that reappear just as you've bought new ones — and the adjacent planes inhabited by entities capable of stealing things. In the most conspiratorial stretch, an artificial intelligence under Denver airport sneaks in, along with a TV series and a 47th president. None of that has any empirical backing. The suspicion that does survive scrutiny is more boring and more uncomfortable: memory rewrites itself, and sometimes it does so against everyone else's recollection.

Why memories get worse every time you tell them

Every time a scene is recalled it is saved again, and in that saving today's version slips in. Objective details are lost, the context blurs — the place, the time of year, who was there — and the gap is filled by a narrative that makes sense of the whole. These are copies of copies. Vivid dreams do the rest: they are remembered as lived and later claimed as one's own. So are films, and those documentaries watched as if they were notarial records. The upshot is that two people can have been in the same place on the same day and keep two different films of the same footage.

With this material you can't prove any broken timeline. Nor can you rule out that someone remembers better than those around them, especially when the awkward memory is that of a botched job with witnesses. If the trend continues, in ten years there will be two camps for every after-dinner anecdote: the one who lived it and the one who swears it never existed. And probably neither of them is lying on purpose.
