And turns out Virgina Tech does a bunch of helmet impact testing and maintains a ranking list https://www.helmet.beam.vt.edu/. The latest helmets have a releasable layer that absorbs (converts rotational energy?) more impact.
This HUD is pretty slick. In a way, it's more preventative (avoiding accidents) vs. reactive (absorbing impact in an accident) safety which sounds nice.
To my knowledge, the only group that tried to test bike helmets against a car is Volvo -- and all helmets failed.
I guess one reason people are so focused on that is because it's easy to quantify.
US or globally? Got any stats to link to on that?
Helmets reduce the risk of head injury by 48%, traumatic brain injury by 53%, facial injury by 23%, and fatal injury by 34%.2 Pediatric non-helmeted bikers have a 3-fold higher risk of serious head injury compared to helmeted bikers;3 one study suggests that helmet use may reduce the risk of head injury by 83%.4
Bicycle-related head injuries and deaths have decreased in states that have enacted bicycle helmet laws.5
Larger effects are found when legislation applies to all cyclists than when it applies to children only. 6
That one study has been thoroughly debunked...yet decades later it still gets cited.

I don't get this fanatical defense of no-helmet-at-all-fucking-cost stance many here often express. I personally know a person who died in bike accident helmet-less, she went head first due to slamming front brake too hard, straight on the head on tarmac, no complex situation, it was more than enough.
I had similar situation - new xc bike bought cca 2007, for the first time buying helmet, spent whole childhood and adulthood without one. Within 3 weeks, I had to slam brakes on narrow winding forest path due to my GF stopping abruptly behind the corner. Don't have memory of that situation, remember opening eyes while laying on the ground, looking at crumpled helmet and visor, and seeing how my forehead went perfectly into a sharp stone sticking out of the ground, not much cca 5cm. More than enough to kill me, and GF told me I hit the ground with quite a bit of force.
I have friends with broken collar bones, shoulders, wrists, scars on heads, from various common bike situations, mostly in the city. Many were skeptics, all of them wear helmets now (sometimes due to hard push from their SO). Most of our friends are doctors due to my wife being one, every single one of them had to do some time in emergency in biggest Swiss hospital, and every single one of them had seen rough head injuries including death from all those folks who swore to never wear helmet, it limits their view (bullshit), their senses (huh?) and so on.
Every single sport facing death risk is maximizing their survival chances by smart behavior and better equipment, which often include helmets. But somehow these folks feel like (since this is hard emotional debate, not factual one) they are outside normal risk envelope thats valid for every single living thing on Earth.
But sure, don't wear the helmet, but lets agree you will cover full lifetime costs of any injury treatment to head/neck/shoulders, including all after care due to permanent disabilities. And don't whine when your kids die because daddy was a bit fanatic and picked up wrong hill to wage their insecurities/arrogance battle on.

And he notably has nothing to say about any of the other numbers and consequences mentioned by the ACS.
P.S. The 1989 "debunked" study isn't even what ACS cited! Their citation was an overview paper that used a broad range of studies: https://pubmed.ncbi.nlm.nih.gov/10796827/
There is a grain of truth to the anecdotal claims. But, even then, this is very much an imagined grain of truth. What makes it fun is if you work for a specialist bicycle shop or up the chain, distributing thousands of helmets. With customer interaction at the showroom level, fitting hundreds of helmets, then selling gazillions at B2B, the question has to be asked, where are the broken ones, the one sent back for money off, as a replacement discount?
Indoctrination into the polystyrene club is also very easy. Customer buys new bicycle, customer gets upsold a helmet, as an easy win. The far more practical high vis jacket costs $5 and you make no profit on that, whereas the $50+ polystyrene is just money for the taking.
The testing was originally to a SNELL standard, but the helmets were too heavy. So manufacturers switched to the lame self-test consumer testing, 'trust us bro'. This became the new benchmark, anything aiming at SNELL or other meaningful test just did not survive the market.
Hence I keep it simple. If cycling for conspicuous leisure purposes (fitness, racing, stunts) then get the helmet and make sure the straps are tight. You will need it for organised events so you might as well get used to wearing it.
If not cycling for conspicuous leisure purposes, but merely for transport, whether that be the commute or errands, then you don't need a helmet. Get the lights, mudguards and high vis instead.
I am learning the counter-logical-fallacies, so I can counter the life saved anecdote with quality nonsense that has the same logical fallacies. For example, "I know a true Scotsman that has been cycling every day for fifty years without a helmet. Once he got hit by a car and his life was saved because he was not wearing an ill-fitting helmet, he would have been strangled by the straps had he been wearing a helmet, plus the driver would have given him less room, so the accident would have been far worse."
I digress, as for the article, the helmet is excellent for conspicuous leisure cycling. Now give me your money!
Thanks for sharing. Interesting to see my Giro (with MIPS) has... 3 stars. Hmmm.
Too many helmets hit the old five star threshold, so to differentiate it's now based on relative performance (the x% best helmets get 5 stars) instead of static thresholds.
A crappy helmet with MIPS is a slightly less crappy helmet that may still be worse than a great non-MIPS helmet.
Like upgrading a 1960 motor vehicle death trap’s 2 point seat belts to 3 point. It’ll help, but it’s still a death trap.
Considered these things a gimmick (any technical equipment bought has list of various tech used within, I generally ignore that by default since I have no idea what each means), happy to see move for more safety in this area. Even small steps matter.
I will climb in big heat wave we have here in Europe now this evening, more sweaty = more slippery on polished rock crags, risk is always not as far as we like to think.
VA Tech (and others, IIRC) has years of empirical tests that show otherwise. What is your comment based on?
Edit: In fact, if I understand your analysis, humans won't get concussions at all.
GP provides no evidence for that. VA Tech not addressing it (if it's true that they don't - I have no reason to believe it) is not evidence. VA Tech also doesn't address my theory that microscopic super-intelligent aliens affect helmet response.
My Lazer Genesis Helmet is a MIPs and it’s the lightest helmet Lazer made at the time.
Much more breathable than my previous helmets too.
Sure, buy all the safety equipment you can afford that has any possible benefit.
What’s better: a $15 more expensive bike light or a $15 more expensive helmet with MIPS?
How are they testing it in the lab? How do concussions work in realistic situations (is there one way?)? What is the distribution of realistic situations?
Maybe the benefits are better in realistic situations; maybe the lab tests are more aggressive than reality or the results are interpreted conservatively (because scientists spending years on something might have thought of a 30-second hot take), ...

MIPS? Or is there something newer
That is important and useful, and is best used in combination with other testing: Bicycling also has many other and more serious risks to cyclist head, including skull fractures, brain damage, and death.
Consumer Reports is another great source (better one IMHO); in their labs they do empirical testing for other outcomes of ~150 helmets, and provide a comprehensive guide to buying helmets:
https://www.consumerreports.org/health/bike-helmets/
In Consumer Reports’ tests, we strap helmets onto “head forms” that simulate the size of a human head, then drop them 14 mph onto a flat anvil to find out how well they withstand impact. An electronic sensor inside the head form monitors the force that would be transmitted to a rider’s skull in an accident.
To ensure the helmet will stay in place during an accident, we test the strength of the chinstraps, attachment points, and buckles by dropping a weight that’s 8¾ pounds and 2 feet so that it yanks on the straps to simulate the force of a crash.
Our testers also evaluate each helmet for ventilation, fit adjustments, ease of use, and other features.
I'm anti MIPS
If you have only tried first-gen MIPS, I recommend giving it another shot.
I ride on the streets of Oakland every single day and situational awareness is critical. The single biggest thing you can do for safety is watch each car as it approaches behind you for its speed and trajectory. Anyone approaching too close or too fast is a bad sign and with a mirror you can more easily avoid them.
These are also available on Amazon and I am not in any way affiliated I just think they’re good life saving technology:
I tend to prefer helmet mounted and I glue them on which isn’t my favorite thing to do on a new helmet. It’s also a bit frustrating when you find yourself cycling in a country that drives on the opposite side.
I do find that on very long tours the week following I’m looking where I’d expect the mirror to be when I want to look behind me.

maybe there will be some engineer on the project who learns something useful while working on this that can be applied to some actual project, but this is pretty clearly not an actual product that they intend to sell in anything more than single-digit quantities
Also, helmets are meant to be replaced every couple of years as the materials deteriorate (UV/heat) and the protection dissipates.
As we like to say, dentist helmet.
Not necessarily:
But if you really like your old helmet—and it’s in good condition—one scientific study tested older helmets and showed that holding on to one for longer won’t necessarily put you at significant risk. Randy Swart, executive director of the nonprofit Bicycle Helmet Safety Institute and former vice chair of the helmet and headgear subcommittee for ASTM International, a nonprofit, voluntary standards-setting organization, says that his own helmet is “much older than that,” though he adds that there may be other good reasons to get a new helmet, such as more protective technology included in some newer models.
How can I get people to stop laughing at me for tinfoiling my helmet?
It's not needed on everything but I really appreciate the extra options on my recumbent and touring bike.
Tolerances on a 1x setup are also much tighter, not ideal for long distance cycletrekking adventures.
Also, with a front derailer, dropping the chain to a smaller cog in the front to get to a lighter gear results in much happier shifting than having to lift the chain to a larger cog on the rear derailer when going uphill.
When MTB racing you can really get some advantage out of shifting combination discipline using a front derailer, when going from a downhill into an uphill.
I'm sad it's hard to find a 2x setup on new bicycles nowadays :-/
Don't apologize for being a human being. The world needs more of them.
Pogies are great but don’t do you any good off of your bike.
Just what I need, when a car nearby me crashes into a physical object, my vizor helmet is shouting "Bonzai!!!" with lighting bolts everywhere.
I really just want a basic, simple HUD that can display speed, distance, pace, HR from other sources. I don’t care about it being standalone, I already have a bike computer, phone, and watch.
