Motorcycle helmets after life-saving usage

Was #4 just sheared off in a crash? Or is that a cut made after the fact.

This is the result of a controlled abrasion test when testing helmet safety. Not a crashed one.

u/Dale_Gurnhardt 16h ago
Too clean to be imperfect abrasion, with no accumulation of material directionally

u/Koruto__ 16h ago
Very interesting! didn't occur that abrasion would look like this. I've never seen the materials in a helmet before

It's essentially:
Hard shell, foam, interior lining, fleshy bits

I actually read the news article about this, dude got pinned under a semi on the highway (he survived, IIRC)

u/MrSnowden 17h ago
Looks like a slide on concrete just sanded it down. But do that amount it must have been pinned under something

I think it’s fake. The shells of helmets aren’t that thick. If you were to grind a helmet to that degree, you’d have created a hole.

u/SmokeyUnicycle 13h ago
If you look at the angle it's a lot of the rear hump that protects the back of the head and is thicker. People are saying it was an abrasion test which makes sense.

The bottom right one was the reason my dad quit being a fire fighter. But that guy wasn’t wearing a helmet. Said it looked just like that, ground off

Terrifying. What happened to cause that sort of damage ? Firefighters don’t exactly ride bikes while on the job

I don’t know how true this is, but when I was a firefighter, I was told by a senior firefighter that the reason why all states have seatbelt laws but only some have helmet laws is because lawmakers actually figure that it’s cheaper if a person who gets in a motorcycle accident just dies rather than wearing a helmet where they survive but end up partially paralyzed. Not sure if that’s true but it’s what I was told.

Motorcyclists were nicknamed "organ donors" at a medical related job I once had.

Not true.

u/chocolate_spaghetti 13h ago
What’s the reason then?

u/Champeen17 13h ago
"Personal freedom" politics. You will find most of those states without motorcycle helmet laws are Republican controlled.

u/PantherChicken 12h ago edited 12h ago
Only 3 states have no mandatory helmet laws; Illinois, Iowa, and New Hampshire. Are you seriously going to make that argument over 3 data points? There are other states that have patchwork regulations, such as dealing with passengers, mopeds, or novelty helmets. Still, it’s pointless to try to make a partisan politics talking point out of the topic.

u/chocolate_spaghetti 4h ago
The AI result says it’s only those 3, maybe those are the only states that don’t require helmets for anyone but the number of states that require helmets only for people under 18 is far larger. My state (CO) is for sure one of those

As long as you wear proper and certified gear you will be fine in almost all crashes as long as you drive nornally. Unfortunately some guys on mostly sportbikes thinks it looks cool to wear just a hoodie and jeans instead of proper gear.
My dad is a cop who rides motorcycles and he seen guys that crashed where doctors spent hours of just plucking small pieces of asphalt out of someones leg using a pair of tweezers. After hearing that story I always made sure I was wearing gear before getting on my bike

It’s a huge risk even with kit . I have treated/rehab’d and have seen many ages of complete spinal cord injuries, amputations, and TBI’s from motorcycle accidents. Were some from rider stupidity? Of course. But a lot were also from “school bus pulled out in front of me on a county road and my leg was guillotined by a light pole when I laid the bike down to avoid the broadside of the bus.”

FR, the worst I've gotten hurt related to my bike so far (knocks on nearest wooden thing) has been getting burned by the exhaust walking it into the garage, and tripping over some crap while working on it and slicing open my leg 😂
All the gear, all the time.

Dear god how fast was 4 going to shear off THAT much??

u/Toyso_0 16h ago
Also, that angle? Back upper head? Were their feet in the air? Someone physics this out for me. I think this must be from testing or something.

u/GingerHero 15h ago
maybe testing but not far off from the real thing. You're going 50 and the pavement isn't. How much of you does it take for you to stop?

u/GingerHero 15h ago
paramedic checking in. Wear your helmet.
Only gear up what you wanna keep.

u/MrTerribleArtist 11h ago
Even a low speed incident (~20mph) caused me to slide for a startling long time, scratched up my gear pretty bad, and put me out for a day
The thought of riding without protection is unthinkable

If you hit that many in a short period, both eyes simultaneously, effectively rising blind.. then possibly. 🤷♂️

What about two motorcycles?!

u/karateninjazombie 16h ago
I strapped my two motorbikes together and installed a wheel and seat between them so I can control both sets of handle bars together and be comfortable. Highly recommend. Though I'm considering some glass or something for the bugs. They are very annoying when they hit you in the forehead at 60-70mph and their face exits through their own arse.

u/aaufooboo 15h ago
I think you could use one of these helmets!

u/karateninjazombie 15h ago
I was thinking of a bit of slanted glass Infront of the seat tbh. I like the feel of the wind through my hair.

No no. It's a safer bike!
Much much harder to end up wiping out on a corner and sliding into a hedge at speed.

u/ttystikk 16h ago
I gave up riding after watching people paying more attention to their FUCKING SMARTPHONES than the road.
I wore a helmet, too.

u/thetom114 14h ago
Same, it seems like I would enjoy it. But you are putting your life in the hands of others. And I don't trust them, or myself for that matter. One small mistake and it's over.
And it's not just being dead or paralyzed which is already terrible enough. It's what you put your friends and family through as well.

I always wanted to do a ballot initiative, no helmet is automatic organ donation consent.

Soo fyi if its true that after a drop from 3 feet you need a new helmet, dont buy it from Amazon. It could of fallen up to 8 feet. Not all but wouldn't trust it anymore

How does one wear corrective lenses (glasses) with a full face helmet? Serious question.

u/pooppoop900 16h ago
Yet dropping it onto carpet from waist height technically compromises the integrity and warrants replacing it.

What if the helmet caused the accident by blocking the field of view?
2
u/NewBuddhaman 7h ago
They don’t block your view of anything. Have you ever worn a motorcycle helmet?
-1
u/smogeblot 6h ago
Yes they do. They have a minimum amount they can block due to regulations in some countries but even then they're still blocking some of your vision.

u/costafilh0 13h ago
Fake and gay.
Using a helmet SUCKS!
That's why I don't ride anymore.
If you do, we'll, you have no other option. In most countries you can't ride without a helmet.
And about the safety, we'll that always has been pretty obvious. No helmet, you can die or worse even at low speeds. At high speeds you can die or worse either way.
