HANS has an even firmer hold on FIA-sanctioned racing (e.g., F1 and touring cars) than it does in the US. The big-dollar teams can also afford to design the entire seat and cockpit around the device, using the car to provide lateral protection.

My understanding is that in F1 for example, HANS has made custom units. I'm not sure how far down the line custom units are available.
Bruce, that's great that people 'walk away".... but really, so? WHY they walked away is COMPLETELY unknown to us. We don't have the information to make the judgement. Maybe it was the seat?? Or the foam containment cell? Or maybe, even though he was bouncing around a lot, no individual impact imparted significant stress or G loading to his body. You just don't know. So, lets not toot about how great the HANS he was forced to wear is.
I tried on all the major players the other night, in Greg Amys car. I was shocked at how the HANS has zero adjustment to the tethers. They are what they are, no matter if you're a tall big guy with no neck, or a tall big guy with a giraffe neck. (Or some other combination). My head went pretty far forward and down before the straps hit. Then it felt like I was a dog that just hit the end of the leash. My head
hurt after a few of those "what if" head tosses. To me, I'd think that one size doesn't fit all. Performance MUST vary from person to person, no?
Well, we just don't know. Call SFI and they will refuse to release any data except to say it passed the minimum level of acceptable in their required tests. HANS reports only the data they want to, and only from the dummy they use. (mandated by the 38.1 spec). (Which, in HANS case is pretty much of their choosing, LOL)
The other one I tried, DID have adjustable tethers. So you can get them perfect. But what's perfect? And whats to stop somebody from loosening them to ineffectiveness?
The Hybrid was really tedious to hook up. Threading the D rings through the helmet loops....uggg. And the arrangement of the shoulder fulcrum piece and all the straps made just getting the harness and everything situated pretty dodgy. I wasn't a fan of all those straps either.
The R3 was most comfortable for me. The thing that goes down you back fit me fine. And it was pretty easy to fit and hook up.
None of them limited my head movement in any significant manner. The halo seat (a Racetech) was the guilty party on that count.
In the end, one thought kept pushing forward. My old unit, the one I've been wearing long before SCCA even discussed recommending something, addressed each and every concern I had as I tested the options I have to choose from. It self adjusts to your geometry. It doesn't hit you like a dog on a leash. IT provides better lateral support. It's easy to hook and unhook. It's off in 1 second.
For me, this mandate is a HUGE and $2000 step BACKwards.
