I’ve been sent this at least three times in the past couple days, and I absolutely understand why. It’s a tiny, wonderful footnote of automotive madness that defies all reason and yet somehow exists under a veneer of rationality and scientific research. As far as I can tell, this blurb in the August 1965 issue of Popular Mechanics is the only (English language, at least) reference to this particular device available online. Which is tragic, because I’m dying to know more about this remarkable thing.
I’m supposed to get up early tomorrow to get on a plane to go to the Slate event in Los Angeles, and here it is almost 1:30 am and I still need to finish packing, but Cold Starts have to be started, coldly, so here I am. Why do I do this to myself?


Oh, back to the thing! Here’s what I’m talking about: a device, developed in Yugoslavia, that lets you, finally, control your car’s brakes with your eyebrows. Yes, eyebrows. Look:
So, what we’re looking at here is a special pair of glasses with a pair of electrodes that make contact with the muscles right above your eyebrows, the ones responsible for moving those two furry caterpillars above your eyes. When you move those muscles, the electrical current from your muscles are picked up by the electrodes, amplified considerably, and then that current is used to actuate and electromagnet that pushes the brake pedal.
The blurb claims there’s a 75% improvement in reaction time when comparing eyebrows to legs and feet, and while this seems to be generally supported by experimental evidence, I still have many, many questions. Other than the fact that people probably won’t want to wear a pair of freaky glasses with little arms that caress your forehead, there’s the question of inadvertent braking caused by emotional responses like surprise, anger, befuddlement, swankiness, disgust and more, all of which are expressed, unconsciously, via our eyebrows.
Would this system mean cars would be screeching to a halt every time a saucy double-entendre is uttered? Would making the Spock-type one-arched eyebrow send you into a spin? And what about brake pressure – is this an on/off system, or does the intensity of the eyebrow motion correspond to pedal pressure?
Who was asking for this, exactly? Did it all come from the realization that eyebrows react quicker? Is that it? I can’t think of any other plausible reason, really.
I can only think of one other sort of interface like this that utilized the muscles in one’s forehead to control things, and it never actually made it to market: Atari’s Mindlink System.
Yes, around 1984 Atari, the videogame company, was experimenting with a headband a player would wear, and that headband would read brainwaves to control a game! Well, that’s what they wanted you to think, at least. In reality, the Atari Mindlink headband did exactly the same thing that Yugoslavian eyebrow-brake doohickey did: read electrical signals from contracting forehead muscles.
It never worked all that well, and as a result, never made it to market, only existing as a few prototypes. I suspect this is essentially the same fate as the eyebrow-car-brake-controller, only if the Atari thing doesn’t work, nobody gets rear-ended so hard their face hits the dashboard, sending their teeth flying around like shards of a porcelain vase packed full of firecrackers.
So, I guess the takeaway here is if you’re planning to design something that’s controlled with forehead muscle impulses, maybe take a pause and reconsider things.
In an alternate world I’d like to think this is how Dwayne Johnson became a NASCAR driver.

*goddammit, Maymar beat me to it
I can’t believe you didn’t make the connection between this and your buttock-activated braking system, Jason! This could be modified to be a much better system than the wedge-shaped thing you came up with. Just stuff one of these electrodes up your tush and voila – the electro-sphincter braking system (ESBS), which I bet is at least a half-second faster than the eyebrow system, and less prone to accidental activation.
i’m sorry, sir. or safety policy prevents us from installing the pucker-braker ESBS in porsche 911s.
I can’t help but(t) wonder, how would this be affected by flatulence?
Well, that should be the opposite of a clench, so I think you’d be, “giving it the gas” so to speak.
I see. And what if you have a case of (Torch’s favorite) explosive diarrhea? Surely there would be clenching involved?
Well, then you’d better stop and get to a restroom STAT!
Indeed!
I knew a woman who could stop traffic with her ass.
Now I’m curious as to whether it is any brow motion? Or do you raise your brows like you’re surprised? Or lower them like you are angry? Or is it programmable depending on your driving style?
I think DT or Mercedes should do a deep dive on this fascinating bit of automotive trivia.
This article made me think of Tenacious D for some reason…
How ’bout the power to kill a yak from 200 yards away…
with mind bullets! That’s telekinesis, Kyle.
Might be useful as a handicapped-driver modification, but the involuntary eyebrow movement issue still applies…
All I can say is that if it was developed in Yugoslavia, it must be one of the most advanced systems ever and anyone who disagrees just doesn’t understand. My newly acquired, beloved Yugo is proof of the incredible quality of engineering that country has to offer!
I’m picturing a world in which Eugene Levy and Peter Gallagher are the world’s top racing drivers, and the Rock has spent years learning to work his left eyebrow instead of the right to excel in Nascar.
Just imagining DeForest Kelley working the brakes with his quizzical expressions….
…ya think he could get the USS Enterprise to drop out of warp with those eyebrows?
Dammit Jim! I’m a doctor not a starship jockey.
Leonard Nimoy and Sir Roger Moore are the respective US and UK senior statesmen, having battled it out on track decades ago and having since resolved their differences.
Burt is the official series mascot and talking head.
I could see how this would be confusing to people who aren’t of Balkan descent, but from personal experience I can tell you that even at only 1/8th ancestry, our eyebrows are very powerful.
Suddenly, everyone with botox can’t stop their cars.
While this idea of squint to brake glasses seems unnecessary and stupid on it’s face, if you’ve got a SO/In-Law or other often-shotgun passenger that loves to criticize and panic about you not braking soon enough, kindly offer up a pair of these glasses to them and I guarantee that behavior won’t last more than 7 or 8 stop lights!
This article sent my eyebrows into uncontrollable surprise, anger, and befuddlement. Thankfully they have restored to their standard swankiness.
That’s fine – but what I really want is for my eyebrows to stop other people’s cars.
All you need is an ex cop car. Then everyone will either slow down or stop for you.
I still get wary upon seeing a Crown Vic in the rearview, even knowing most have long since been retired. The Explorers are just evil…
I was unaware that we were KINK SHAMING this early in the morning!
Only while driving. Keep your kinks off the highway.
You’re not my supervisor!
Ok well do what you want, but expect to be shamed if you’re kinking on the freeway. FOR SHAME!!!!!!!!!!!!!!
Where else am I supposed to act out my Highwayman fantasy?
Get your kinks on Route 66.
Apple later expanded upon this idea for their ill-fated forehead-muscle-controlled search engine, iBrowse
Aaaaand COTD on the first post of the day.
You get outta here with that nonsense. Go on, git!
