Rendering and analysis of RoGro's crash
Thanks to YouTube recommendations, I stumbled across this video. I even had to complete a survey to be allowed to watch it.
Anyway, this to me is a very fascinating 3D rendering and explanation of the crash from multiple angles. Angles the cameras there that day would not allow us to have to further help us wrap our heads around the hows and whys of this freak accident.
This only reinforces further just how effective the halo is as a safety device and also better illustrates how much of the severity of this crash could have been reduced with a different barrier design.

That's an incredible visual. Every time I see more coverage of this I get the chills. A true testament to modern safety precautions in F1.
It's amazing that they were able to reconstruct it with so much detail considering there was a car one moment and a giant fireball the next.

If you do anything often enough, everything can happen. Hence Roman is shunted off at a place that few cars are and through an unprotected guardrail where only the Halo would save him.... I wonder if an indycar windshield would have fared as well?

@dieseldub Hey this is really neat! Still can't believe he got himself out of there.
@racinbob yes, it would have. The aeroscreen has a halo structure behind it.

@dieseldub armco is the honey-badger of racetracks. It does what it does and doesn't GAF what you wanted it to do.
- stop oncoming car without rebounding it back onto the track? check
- bell curve g-forces rather than a spike and decay? check
- prevent penetration into non-track surround? check
I mean it's 1930s technology ("Originally invented by the Sheffield Steel Corporation of Kansas USA in 1933, the design of the crash barrier has largely remained the same to date....")
It's not the best solution, but it's better than most of the alternatives, right? And I say that as a fully-certified volunteer lifetime member of the guardrail-testers-union. Thanks for saving my life and Grosjean's life, ARMCO.

@dieseldub Neat. It's even more impressive when you realize just how fast things happened and how little margin for error there is for the drivers. He went from racing to on fire in 2 seconds. The same thing could happen in a split second to any other driver on the grid, and they need to keep it together for the entire race.

@jayvincent For cars, there are also the tall catch fences that keep the car from flying into the stands and taking out crowds of people. Those are a modern invention, along with the computerized engineering tools that just didn't exist when ARMCO was designed. Look at the runoff in places like COTA, for example.
For bikes, there is air fence - basically a big squishy airbag set up in front of the ARMCO in particularly dangerous corners. I've fortunately not tested it, but have seen others walk away from crashes that would leave them dead if it weren't there.

@dieseldub Thanks, good to know.

Yup. Even after watching this reconstruction I struggle to figure out where his body was positioned when the car came to rest from the photos alone. Simply staggering he was able to survive this.
@jayvincent It's simple and does pretty well considering the cost and simplicity.
But the FIA and F1 are about being the latest and greatest. They already require tracks to have facilities up to a very high standard for even just garages. There certainly have been some amazing advances thanks to computer technology and innovation in the intervening years.
Armcos work very well for cars that don't have a very skinny nose travelling at near 140 MPH and piercing through the separation point between the two pieces of steel...
It was a freak crash, but that's where most innovations have come from. Freak happenings that no one thought of before it happened for the first time. Though, I believe there HAVE been F1 cars going through armcos like this before, it just hasn't happened in a long time. And the previous times, the drivers didn't survive.
The halo is another instance of that. A large part of its development stemmed from two instances. First was Felipe Massa getting walloped in the head with a bit of spring flying off Jenson Button's Brawn in 2009.
Second was Jules Bianchi sliding off a very wet Suzuka and going underneath a crane trying to extricate another car in the same gravel trap. There was an obvious mismatch in the height of the two vehicles and the car submarined under the crane, right at the level of Bianchi's exposed, but helmeted head.
A halo and having upright/wheel tethers would likely have saved Senna's life, too.
Point being, there's always a new circumstance that was previously unaccounted for that in their aftermath, smart engineers and rulesmakers come up with solutions to try and prevent such things from happening again. Progress is a good thing.
Armcos are still great for lower speed, wider frontal area road cars, especially for the cost. But F1 is at the extreme scale of performance and car design and as such, the track barrier designs require improvements when we have moments like these that clearly show there are obvious ways to have made this a much less severe incident by revising said barrier.
