Whose actual idea was this, as I can't remember. Everyone over the last couple of years just seems to have accepted its introduction as inevitable, rather than coming across as the main backer of the idea

The Halo was originally a Mercedes answer to a GPDA question asking the teams to come up with something which is quite ironic really in that Toto wants to take a chainsaw to it

Regards the Bianchi accident i'm not even sure the Halo would of still been attached to the car, from memory the roll hoops themselves are designed to take a backward force of about 7 tons and it sheared that cleen off, i don't for one minute think it would of deflected the car to the side of the digger, i think the best solution to that accident and the reason it happened was the most simplest and that was the VSC

do we really need all these images ??

I'm not sure i've ever seen a simulation of Jules crash to say one way or the other for certain ...you can't read too much from the roll hoop being sheared as it took the full force straight on & i'm not sure the halo would've (it certainly looked at the time from the pics that poor Jules had taken a glancing blow)

IIRC the car was travelling pretty much directly forward and hit the truck at a very fine glancing angle so the force on the halo would have been mostly pushing it sideways. The question is whether the halo could have provided the ~6 inches of deflection in the car's path necessary to push the air box and driver's head around the back of the truck. Since the primary goal of the halo is to protect from impacts from in front, I doubt it's hugely strong when pushed sideways.

Even had the car been deflected, it still would have been a very big hit, but not hundreds of G.

As others have said though, that accident was easier to solve by other means - namely making sure people aren't driving at racing speed when there's a damned great crane inside the tyre barriers.

I think one major issue is that drivers are needing a little step to get in and out, to climb over this thing. That can't be good.

My personal opinion is that this is going to do more harm than good, and will probably be a factor in a major accident, whether by it obscuring someones line of sight (and it clearly does), deflection of an object into their body or similar, someone being trapped, or something else.
I hope I am wrong..

I think that's only because they can't touch the halo for fear of damaging the delicate aero appendages attached to it. It'd be easy enough to get in and out if they could put force directly on the halo (which in the event of a serious accident they obviously would).

Would a driver be able to exit themselves if they had a shunt like Alonso Melbourne 2016 where the car is upside down next to the barrier?

[Evangelion]

I'm pretty certain the answer to that is a resounding no!

I read somewhere that that was one scenario they examined and they found it to have no detrimental effect on his ability to extract himself in the case of that accident.

[angrymoby]

how long do we reckon it will be before we get a 'thank fk that he had a halo, otherwise he'd probably be dead' type crash?

I'm going with 10 races in ...& probably involving Alonso

[Evangelion]

Considering that only one F1 driver has actually been killed during a race in over 20 years (and a halo would not have saved him anyway) ... I'm going with another 20 years.



A halo causing more problems than it solves ... 20 laps.

But you don't need a potentially fatal incident to vindicate the Halo. There have been numerous accidents over the last few years of cars riding over one another's tub in a potentially dangerous way that Halo would help with. (SCH/LIU Abu Dhabi, ALO/RAI Austria, ALO/GRO Spa etc)

The problem exists that the Halo is the best solution that the FIA have found after testing, and they are pretty much forced to fit it given that if a preventable accident happened without it there'd be significant legal fallout.

Remember this device is only v1. It'll change and improve over time as with everything.

the last 2 drivers to die in F1 have both been because of blunt head trauma ...& whilst no one can say with certainty a halo would've saved either, i'm pretty sure it wouldn't have made things worse.

not entirely sure what a bigger 'problem' than death is tbh, maybe death whilst trapped in a burning wreck ...but i have yet to see an impact related fuel fire due to fuel tank rupture, well not since the introduction of the fuel cell/bladder

Car fitted with fuel cell bladder -



I think the main improvement to fire safety in crash impacts has been instant fuel shut off valves and the use of kevlar.

every F1 accident is preventable, just ban F1 and get done with it

[Evangelion]

This morning I watched for the first time, video footage of a moving F1 car fitted with the halo.

Bloody hell, the thing's even uglier than I thought it was!

[8V085]

To be honest, I thought I will hate halos but I don't find them that offending! Some look better some look worse but they are sort of ok. I'm more upset about grid girls and I never paid much attention to them before.

Would it not? I mean rather than just in your opinion? I mean is there actual evidence to that end? Or are you just saying it because you don't like the halo?

Or anything post Lotus 49....

[Rude-boy]

First off i can say that i do not like the Halo and whilst i can see the reasons why it has been forced upon people the way it has i do not agree with it.

I appreciate that it is likely that there will be some lives saved by this device. But then again why are people still allowed to race horses without much more than a couple of bits of kevlar in the right place and a helmet? I suspect that you will find that more people suffered life changing/ending injuries as a result of being kicked in the head by a horse. Anyway I digress.

My biggest annoyance with the halo is actually that I do not believe that it is the right solution, insufficient testing for a start. More so you read about the canopy that the Americans are trying out and how little of the 'hall of mirrors' effect that people have predicted there actually appears to be on that from reports.
