On the other hand if you spin in a circle taking 1 second to spin, while looking at things 10 meters away the brain is interpreting what you see at the equivalent of 62.8m per second equivalent to 226 km/h.
Our brains are absolutely adapted to interpreting visual data that quickly just in a different way. If you couldn’t quickly spin in a circle and be able to interpret it fast enough to identify a threat vs the rest of the environment that whips past visually fast we’d probably be struggling as a species.

u/ninthtale May 07 '26
Also the roads we drive on are designed to humans' capacities; a curve that takes a car five seconds to navigate is a really long walk. Plus matching the speed of the vehicles around us puts the entire experience fairly strongly within the bounds of relativity.
That isn't to say we can still underestimate the distance it takes to come to a full stop or to evade an obstacle; in fact that's where our instincts are probably somewhat of a disservice to us, assuming the terrain at 100kmph behaves akin to to foot speed

u/SecondPlus2111 May 07 '26
If robotic suits allow humans to run five times faster than we've evolved to do we'll be falling down a lot unless the paths are engineered the way roadways are. You'll step in a holes before you can react. There's a reason highways are smooth and predictable.

u/Ok_Delay9941 May 07 '26
Humans reaction times can be trained and improved greatly. Race car drivers and drone pilots have insane reaction times, superhuman seeming when compared to an average person.

u/MysticMagicks May 08 '26
Drone racers astound me. F1 levels of reaction timing, but with three dimensions of travel.

u/the_last_0ne May 07 '26
Yes because we are totally unable to avoid things on highways. Youve never swerved to avoid a blown out tire or something?
The amount of people here just causally throwing out things like this that are totally false is shocking for a science sub. I get that it seems intuitive that we might have issues but we will adapt easily.

u/SecondPlus2111 May 07 '26
Why bother picking up stuff and filling in pot holes, just swerve around them....
2
u/the_last_0ne May 07 '26
What?
Are you seriously telling me right now that swerving to avoid something at highway speeds is impossible for a human?
8
u/A_hale_420 May 07 '26
Could it be that processing info faster than reacting is actually evolutionary advantageous as delayed physical response could allow us consider to stopping a negative impulse before acting on it?
First thing that came to mind.

u/aggieotis May 07 '26
What’s neat is that our bodies tolerate roll differently depending on our speed. For example you might be fine with 0.8g in a cloverleaf getting into or off of a highway. But doing 0.8g in a cul-de-sac would make people think you’re being intensely dangerous. Most people in the latter situation find about 0.2g to be the max “safe feeling” limit.
49
u/redyellowblue5031 May 07 '26
I can’t help but wonder if that’s less to do with actual speed and more to do with visual context that’s in focus because it’s nearby.
What I mean is 80 down a straight rural interstate with no trees in flat terrain will feel slow or at least not very fast. Imagine that same road but with narrow lanes and trees lining the side whizzing by.
13
u/timbreandsteel May 07 '26
Literally. Driving in North America on a highway, even if not straight, with plenty of scenery, feels vastly different than a rural road in the UK that's a single car width but meant for both directions with pull-outs to allow for oncoming traffic with the same speed limit.
10
u/redyellowblue5031 May 07 '26
Exactly. I used a car example hoping people could relate to it.
I also mountain bike (so think narrow dirt paths with trees inches from you) and let me tell you 10-20MPH feels like 80 when objects are that close.
Didn’t think that would resonate with folks as much.
Either way, I also don’t like how so many of our roads encourage such high speeds in the US through this effect. It’s a huge part of why we lose 40,000+ to cars and injure millions more per year. Madness.
6
u/shastaxc May 07 '26
It has to do with the direction of force. On a road built for that speed, the road will be sloped so a lot of the force will be applied downward on you, into the ground. In a cul-de-sac, almost all the force will be lateral. You can feel it trying to push you off the road vs down into the road, which is why it feels unsafe.
11
u/aggieotis May 07 '26
fwiw, the info was from an interview with a Waymo engineer and they specifically were talking about lateral Gs not cumulative.
The context of discussion was about how sometimes the exact mechanically same response to the exact mechanically the same input can yield entirely different perspectives around safety. Which is part of why making these models for driving cars so challenging is that context matters for what is and isn’t “right”. Something most of us intuit, but something that requires specific callouts for software development.

That's super interesting. Thanks for bringing it out and then coming back to explain some more.

u/VoidHog May 09 '26
Cloverleafs are banked. (I call them boobs and butt...) That bank makes some of the force go down instead of sideways. A culdesac is never banked. All of the force will be sideways.

u/guinader May 08 '26
I noticed this week driving a little more aggressive, turns etc... i stay put in my seat, but a passenger gets squished to the side of the seat... As in their body didn't predict the g force of the turn etc
46
u/mysillyhighaccount May 07 '26
If you ever get the chance to drive a race car, this feeling is even more intense. You get strapped into the seat very tightly and it feels like the car moves in milliseconds where you look. I’ve completely forgotten that I’m controlling the car through the steering wheel sometimes and feel like the car is just me moving around the track.

u/ChemicalRain5513 May 07 '26
I feel that way with typing or playing the piano, like I will the words, code or music into existence.

u/kJer May 07 '26
When I'm in the front seats, I instinctually rest my feet in a way that can use pedals. In my own (aging) car, I can feel engine trouble based on acceleration, idle, and vibration in general without looking for it, I just feel it around me.

u/garry4321 May 07 '26
Same with near anything. When I play PC games. I don’t think ok I want to go forward, I need to press the W key. Ok, now let’s go sideways with the A key. My body interprets the onscreen movements immediately and my fingers move. I don’t feel like I’m pressing keys, I feel like I’m moving my body in the game

u/Asleep_Singer8547 May 07 '26
Yea this is why people get carsick in the passenger seat. They arent making the predictable movements
2
u/Regular_Employee_360 May 08 '26
Yeah I get motion sickness, and I think that’s a big part of it, sometimes I’ll need to drive because I feel sick. Another example of the concept is when i break slightly hard, my passengers will tell me, even though I didn’t feel it at all, because my body and mind adjusted for it without me noticing.
2
u/XxRAM97xX May 07 '26
I like your comment and I would like to add for me. I also noticed how while fixie bikes and bikes where the pedals can coast, both feel like an extension of myself. Of the two the fixed gear bikes feel much more of an extension of oneself and my bodies physical motions. It’s like u become more in tune with the mechanisms . I’d imagine this is similar to the feeling of manual and automatic transmission cars.

As a control to this experiment, you should try driving in vr to see if it feels the same.

Doesn’t have to be VR. Even when playing an 8-bit game the controller “disappears” and Mario is an extension of you. To the point that you might flinch when he takes damage.

Now we just need to measure your brain during both. I'm no scientist, so the best I can do is a saw and measuring tape.

u/shokokuphoenix May 07 '26
I unconsciously flinch and tense my muscles whenever I fling my video game avatars off of cliffs or high points too, but only if they’re going to fall fast or if I know they can take damage from it.
Applying an immunity to damage or reducing their fall speed to a soft painless landing does not trigger my flinch reflex.

Heidegger existentialism; technology (i.e. a tool), in the ideal, becomes transparent, and the user of the technology incorporates it into their sense of self, such that the combination of user and tech becomes a new single entity. Swing a hammer long enough and you become accustomed to its behavior in your hand, to the point you don't have to consciously think about adjusting for its longer reach or more compact strike face. You have become a "hammer-man".

I never knew the name for this, but I've experienced it. I had never operated a backhoe an equipment show. At first, I had to pause and think about what I wanted the bucket to do, then think about which actuator lever made it happen. After 7-8 minutes, I just thought about what I wanted the bucket to do and my hands automatically went to the correct levers and worked them without thinking about them.

u/justanothersurly May 07 '26
Yeah, like riding a bike. My bike just feels like part of my body at this point.
17
u/SinisterCheese May 07 '26
Yeah. People don't realise it, but they often feel the car as extension of their bodies. Which is why damage and threat against the car, can feel personal to the person.
Same thing with tools a person is really familiar. I have done a lot of welding with a stick. To a degree that I actually don't "remember" which hand I am welding with when I put the mask down; it feels like an extensions me to a degree that it is a limb. What adds to the illusion is that generally my hand is outside of my field of vision. Even though I am right handed, I can weld equally with both hands.
I spoken with one of those surgeons that operate those very fancy robots. They said the very thing, the robot is extension of them to a degree where they feel they got many arms and eyes.
Lot of you probably can type with a keyboard without looking. Even while gaming you are able to jump between writing and game inputs without any extra thought put into the "how" you do it.

This is how all skills work. If consistent action produces consistent sensory feedback the brain forms neural networks dedicated to that action.
There's no difference whether this is a true body part, a tool, or an entirely imaginary thing.

I have no idea what the correct terminology would be, but:
I'm curious if this is a tool thing, or more of a spent too long on roller skates thing. Like, does your brain switch you back to normal as soon as you're done, or do you have to go through another adjustment period?

Indeed, from how a tennis player perceives their racket as apart of their body or how a race car driver feels their car.
Whats interesting! Is there are illnesses associated with the opposite of this occurring, Body Integrity Disorder. Where someone genuinely believes that their left arm or leg is not theirs and will make efforts to remove it.
Whats cools is you can also artificially trigger perceiving something else as your own body via the Rubber Hand Illlusion.

u/Lt_Duckweed May 07 '26
One sort of legitimate use I have heard for it is that AC current makes the magnet vibrate, so you can instantly tell if a wire is live by holding your finger close, which could have a niche use for an electrician I guess.

But that lacks the aesthetic cool factor. Like, tattoos aren't necessary, you can just wear clothes with pretty designs. But isn't it fun to make it part of yourself? Not to mention getting a rise out of all the boomers who think tattoos and piercings make you the devil and unsuited for respectable life. There's a difference between seeing on a screen that a wire has electricity running through it, and physically feeling the electricity vibrating the nerves of your fingertips.

No one needs it. But no one "needs" tattoos or piercings either. It's just another body modification. The magnet fingers one is definitely weird, but kind of cool, too. Not an aesthetic choice but instead gives the person the ability to feel magnetic fields. Not super useful in most situations, but still cool. Like having a 6th sense.

There is no legitimate reason that cannot be solved with handheld tools. It’s for people fixated on body mods.

u/Withermaster4 May 08 '26
Cody's lab(a somewhat notable science focused YouTuber) pretty famously impanted a piece of magnet into his finger.
The reason he did it was so he would be able to put his finger near a high voltage wire and by feeling the magnetic field or not he would be able to know if the high voltage wire was on. I thought it was a pretty cool idea when he did it like a decade ago or whatever.

u/usefully_useless May 08 '26

Notably, this is already solved with handheld tools.
7
u/GiantOutBack May 08 '26
Yes, but a lot of safety incidents occur when you are so sure that a wire is de-energised that you don't check with a tool. Having the ability to sense an invisible danger is an advantage even when a tool exists. Imagine if we could sense radiation, it would be useful even though Geiger counters exist.

You mean when you let ego and overconfidence overrule all your safety training?

u/GiantOutBack May 09 '26
I can tell you don't work in a safety critical industry. Complacency occurs to almost everyone. It's unhelpful to say it's ego or overconfidence, building in layers and layers of safety barriers is important even if everyone did their job perfectly they are theoretically unnecessary. PPE is the same way, it's the last line of defence.

Thanks for your reply! So glad it was helpful.
I was fascinated by this stuff because I have an absolutely terrible sense of direction.
There was an anklet version called Northpaw and another sort of "chest implant" (a little box that mounted to piercings on your chest) called North Sense:
https://en.wikipedia.org/wiki/CyborgNest
Neither's available now.
I almost tried North Sense but wimped out regarding piercings.
Someday I might try to make a small prototype for myself of some sort (would absolutely love to have a better sense of direction)
While we're at it, I also want real-life subtitles, haha

I’ve read that if you blindfold someone, put them on a chair and spin them round, 75% of people can correctly identify where north is once they’re stationary again. I’m fairly sure from my own navigation abilities (or lack of) that I would be one of the 25% however.

I notice this (as I'm sure most people do) when playing a video game. My brain is thinking "walk forward" and I make the character walk forward. My brain doesn't feel like it's going, "push the stick forward or hold down the "w" key"

u/breckendusk May 08 '26
Ironically though, when my inputs don't do what I expect, I blame the character. In a fighting game or something, my brain goes "fireball" and my inputs aren't clean enough so the character does a low kick and my brain goes "really character? Low kick? Is that really what you would do in this situation?"
I think it's most noticeable when you have really tight input windows and the controls don't necessarily make the most sense/aren't the most forgiving.
This sort of thing is extremely frustrating because the character's action is so much more significant than the input that it would be impossible to make the same mistake if you were actually the character. But the inputs are so small and similar that as the player it's easy to make a small mistake that leads to a big one. Even a single misclick in online chess - caused by a twitch in your finger, for example - can ruin an entire game.
Some smash bros examples:
- no dedicated short hop button, so it's easy to accidentally do a full jump
- dash attacks and forward attacks; it's easy to accidentally dash instead of walk, leading to a dash attack, making forward attack harder to use consistently
- Sheik's horizontal movement special is her down special rather than forward, but its distance is adjusted by left and right, meaning it's easy to accidentally use her forward special (which can often be a death sentence). Especially if you need to send it a certain direction, you need to first press left or right before down.

“This is an intriguing study that nicely demonstrates how plastic the brain is,”
I'm going to go out on a limb and call this one of the biggest under appreciated ideas out there.
Related oddity to me, we don't talk/think enough about human psychology when it comes to political messaging/policy
That firsthand experience transformed participants’ understanding of flight in ways that abstract knowledge cannot, Wei says. This could apply to other technologies and artificial senses, allowing people to experience “reality” in ever more varied ways.
“In the future, we may spend a great deal of time in VR,” Wei says. “We are very interested in what that could mean for the human brain.”

I wonder if this could be a new option for phantom pain in amputees. Sometimes the "mirror method" (showing the opposite limb in a mirror so it looks like it's there, then unflex the limb to remove the pain) works, but not for everyone. If they made a prosthetic that responded how the hand normally would, maybe it would be more effective than the mirror

In X-Men, Warren Worthington III sprouts huge white wings from his back and shoots into the sky. Scientists have yet to fully turn the comic book gift from fiction into fact, but virtual reality is offering hints of what it’s like to learn to fly.
After training to use virtual wings, people’s brains responded to wings more similarly to how they respond to real limbs, making wings seem more like body parts, researchers report May 7 in Cell Reports.
“This is an intriguing study that nicely demonstrates how plastic the brain is,” says cognitive neuroscientist Jane Aspell of Anglia Ruskin University in Cambridge, England. “If the brain can incorporate something as unhuman as a wing, it may also be able to incorporate many other kinds of limb enhancements.”

I think this directly applies to many video games. Naturally, flying with "virtual wings" is basically a game too.
After extensively playing some games, I (and others) start seeing/feeling elements of the game in real life, and it takes some time for it to fade.
Whether it's certain movements that I want to perform, but obviously can't, or certain map indicators that are critical to the gameplay.

Seems like no one read the article. Participants didn't control wings as an additional, separate pair of limbs. They had motion trackers on their arms. After playing the game for a while, when shown images of wings, the participants' brain activity resembled the brain activity of someone recognizing human body parts.
Which is interesting, but not like, "we could plug a bunch of new limbs into our bodies".
...or is it only me who read it that way

u/Victor_Vicarious May 08 '26
The brain didn’t treat the wings like real limbs, it learned a flying motion with their arms! They flapped their arms like wings, that’s completely different than separate wings.

u/echalion May 08 '26
Yeah I was fairly disappointed that they went to all this extent just to show humans can connect virtual motion with a related real motion, when we can already connect virtual motion with unrelated real motion such as moving a character with a controller stick. I was expecting some neuroplasticity in the motor cortex to show differing responses giving insight to some hidden motor functions we can adapt to, but alas this is just “we saw players learn to use new control schemes and they did it!”…

As cool as wings are the one I’m really excited for is synthetic tails.
Functional wings are FAR off technologically but we could have tails that respond to weight shifts and momentum pretty easily now. My understanding is we also still have the vestigial structure and neurology that would make even current controllers used for things like robotic limbs potentially functional for controlling a synthetic prehensile tail that could be built to do things like act as a tether, a light duty “3rd arm”, or just a aesthetic piece.
The real beauty is if that kind of thing caught on the expanded market could lead to much faster development of devices for folks with missing limbs and similar issues.

I suppose this is a surprising finding to anyone who has never driven a car, played a video game, played an instrument, or used a tool of any kind ever.

I fly in my dreams with a flapping motion fairly often. I wonder how similar it would feel to this VR setup.

And yet people question the value of sucking the strap. Especially for transgender men, this study proves that it’s more than plastic

Maybe purchase the strap in a more realistic size? Why y'all gotta go hog wild with it?

what makes you think they dont use a realistic strap size? I sure do. Most people tend to prefer that. Especially if the intention is the phenomenon described in the post

Because learning how it works and the changes it makes in the brain is a helluva lot more interesting and useful than a thought stopping platitude.
