I agree with a lot of that BUT 1 thing I'm not sure on is Dan wheldon. The catch fencing is so strong to protect the fans. I still feel the halo wouldn't have stood a chance.
Yes, it would have protected the driver, because despite there being a serious amount of energy involved, the halo would have had it's part in deflecting the vehicle itself, in extreme terms; the halo would have helped the car bounce away from the structure, or at the very least, avoid / block the fencing to enter the cockpit (area). without the halo, it was an open area and the driver had zero chance. let's imagine it in 2 ways; a knight riding a horse in nothing but some underpants with a battering ram coming straight at him, or a knight wearing protective armor AND mounted to the saddle at the horse a metal cage. would the battering ram still hand out a hard blow? sure it will. would the knight suffer death as a consequence? hardly imaginable!
offcourse it's just an example, but that is more or less what the halo would have done. in this case, dan wheldon wasn't like a naked knight - he was wearing his armor. but to survive a blow from the battering ram (the fence catching), he needed to have that cage around him (halo).
Also people need to stop thinking the halo is some kind of force field. If for example Grosjeans car had hit Alonso's head, it probably would have killed him, if you added the halo to that, the halo if as strong as its meant to be, would have cut through the floor and side pod of the lotus, so plenty of broken sharp carbon fibre is now heading to alonso's head.
i don't think you're looking the right way at how the halo functions. the halo is going to be a structural part of the vehicle itself, which will in result not tear through the drivers like some claw or butcher knife, but it would rather mean that grosjean - upon hitting the halo around alonso's head - would alter the course / direction of the ferrari, and swing it more to the left if any. no, it's not adamantium, so it might even indeed get cracked, but even then it's not a piece of non-safety glass and still that means it absorbed a whole load of energy that otherwise Alonso's head would have taken. conclusion: halo works
Yes the halo would have saved Surtess and Wilson, but im not sure on Maria, Jules & Dan.
how is there any doubt on Maria de Villota? the halo's shape alone would have lifted up the trucks' cargo 'door'. instead, having nothing in front of her, the cargo door LITERALLY penetrated her helmet and only stopped because of the headrests, the helmet's construction itself and the bone of her skull. if it was a 1995 car, with a 1995 helmet, her head would have been literally cut in half perhaps all the way to the back. just let that sink in for a minute.
the diagonal shape of the halo would have saved her life in itself already, hell, the engine cover in itself mounted backwards in front of her might have even saved her.
jules remains a big question mark, hence why it's mentioned as MIGHT. but there is no doubt that it would surely had increased his chances as it would have absorbed some of the impact, whereas similar to maria de villota, jules actually DID hit his helmet - thus his head - to the truck itself. the halo would have taken THAT force, and as such, also took out atleast some energy from the crash. would it be sufficient for survival? huge question mark there. the decelleration itself might have been lethal enough. But, the shockwave that came through the helmet hitting the truck itself caused massive damage to his body (brains) additionally or cumulatively being simply too violent.
in either case - the halo would have taken that physical contact out of the equasion, and would have 'only left him' with the extremely rapid decelleration. hence why his chances for survival would be definately higher. high enough? that indeed is a big question mark.
You guys really love this halo, I dont want to ever catch you guys out cycling without one
cycling is quite the different story to riding an f1 car.
but i talk from experience in going offroading in a bike through forest areas with hill climbs, decents, mudtrails etc, and i have rode it only once without protection as stupid as i was and i had an incident which caused me to have the steering bar to hit my chest and left me with broken ribs, a damaged diaphragm, and a perforated lung. and i was
all alone. i gather that amongst one of the most stupid things i have done in my entire life and it could have cost me my life actually. i was really lucky to be able to make my way a bit further where somebody passed and who called emergency services. apart from that single incident, i always was, and afterwards always after, drove with adequate protection; knee cap protection, shin protection, a fall helmet, a chest plate and shoulder plates, all lightweight but safety approved. i had 2 or 3 collisions afterwards and thanks to one of those, slammed hard into a tree and walked away virtually unharmed bar some bruizes and some difficulty walking the next day through a day of 3 afterwards.
but in daily cycling, there are different circumstances. hence why your daily car commute does not require fia-legislated seats, belts, rollcages, etc.
