Thanks for Posting this Stacy and you are welcome to use my
Simpson fire suite to combat the flames (your on your own
as far as the underware goes!)

The point being make is the usual "Risk Assesment" or Blue Group
talk as I liked to call it. I get calls or emails, at least two a month,
from Corvette drivers totally conviced the roll over hoop
is the equlivent of a roll bar and they feel save using a strong harness
bar with 5 or 6 points belts. It's rare these cars roll over (at least in
track incidents) so there are not many examples to prove or disprove this thinking. However, this incident and its photos support our underlining policies. In this specific incident the driver was better
off with just stock OEM systems and a good helmet and had he been
restrained in a upright position, the head would have likely been crushed along withthe roof. This argument as been around for as long as I've
been doing track events.

This supports the underlying operating system of our Tech Spec and Safetly policies & recomendations Either go stock DOT OR full hog SCCA TT (or club racing) Spec as they are both designed to work as an integrated system. When you take components out of that system it is comprimized.

It also supports the underlying processes we have for assiging run
groups, solo'ing drivers, and chosing instructor canidates. I really
think this was a case of someone managing to get into an advanced
solo group when they should not have but this is the very definition
of every instructors worst nightmare. To me this sort of incident would
be a good case study for an instructor clinic.

Are we going to ban harnesses w/o roll bars: NO. That is the drivers
decision to make. We can not make that decision for you.
Putting roll bars in a daily driver communter car could be a bad idea-it depends on the car and the bar design. A custom made bar may solve these problems for some cars but there will always be some where even a custom bar won't work. Not to mention the loss of the back seat which
may be unacceptable when you must carry passangers.

Stacy's purpose in starting the thread is to provoke thought and
discussion. We really need to think about what we do and the
challanges of running a season safely get tougher and tougher every
year.

This goes back to my point about harnesses enabling a driver to drive a car faster... one of the points of the equal restraint policy is so you don't have a situtation of a driver being strapped in while his/her instructor or passenger is flopping around in the other seat. The other is of course that in the event of an accident, one person is much more likely to be seriously injured than the other. IF both driver and passenger are using stock belts... the theory is the driver will not push as hard as he/she might otherwise, thus reducing the risk of an accident... howver small that reduction might be, its still a reduction.

Stacy,

I will take exception to this policy. The equal restraint rule should be used as a matter of tech inspection. Cars that provide a 5 pt. harness for the driver should provide similar restraint for the passenger. However, if the car meets this requirement and passes tech inspection (in this case, assuming there is no rule requiring a roll bar with harnesses), then the driver has met his obligation.


See above...

Quote:
If an instructor decides at his or her option not to use the harness in favor of the factory seat belt, then that is the instructors choice. The student has provided the option along with an approved second choice (the factory belt).

On a case-by-case basis, that would indeed be up to the instructor... and in general usually IF we are familiar with the student and we are reasonably comfortable in assuming he/she won't do anythng stupid.

Quote:
Let's just assume, for the moment, that you get some whack-job instructor who doesn't like harnesses under any circumstances. Should the student's safety be compromised because the instructor won't use the option provided.


Hopefully that instructor will have asked beforehand not to be assigned to cars with harnesses... but if not, we will find one who is, and put the whack job with someone else.

Quote:
Never assume that instructors are safer or smarter, in all regards, than students. Don't we frequently see more incidents in the instructor group than in student groups?

LOL ... I'm not gonna go there... but your second point about more accidents in the instructor group: Take a look at the cars in the isntructor groups and the advanced groups; I would venture to say that 50% or more have roll bars and harnesses at this point... and I'll also venture to say that an even higher percentage of cars that have been in an accident also have harnessess and/or roll bars

Quote:
We share the same belief about the harness bar and harness example, so if the instructor opts not to use the harness and a factory belt is available, then it would be the driver that is at a safety deficit.

They both will be at a deficit IF the driver proceeds to drive as if he/she were still wearing harnesses. The whole point is to help ensure a driver is not driving above his/her means and putting themselves or their passengers at undue risk.

Quote:
Question:
1. Is the equal restraint rule really applied in the manner you described?


Not in every instance, no. And there haven't been many instances where the question has been raised either. I think (I hope) that if you've done more than a couple events with us, you know that we pride ourselves on being very flexible and accomodating when we need to be.

Stacy, I can't agree more about Triangle Z and THSCC being flexible as well as very safety conscious. For that you are all to be commended.

I agree with the notion of the equal restraint to insure that car owners provide for both driver and passenger. We have come accross a rare example where a passenger, either student or instructor may be uncomfortable with the lack of rollover protection given the use of a harness. As a student considering a ride-along, I would choose another instructor to ride with. Instructors might request be assigned to another student. So, I suppose that situation is highly unlikely.

From my own personal perspective, I disagree with the idea that I drive with a certain mindset derrived from simply wearing a harness. I look at it in the reverse. I've got the gear because I would not drive differently with vs. without the cage, seat, harness, etc. I will continue to go faster as I develop my skill as a driver. The better I get the broader my comfort zone. I inch up on my limit little by little rather than going over the edge to find out where it is. So, since I'm going to progress to being faster and faster, I might as well have the stuff.

Look at another way: having a cage, race seat and harness does not make me any more willing to risk injury or wad up the car.

As orgainzers, its our job to ask the what-ifs and plan and prepare for them. When it comes to OUR participant's safety, we'd much rather be pro-active than reactive.


And I appreciate and understand that. And you have made it clear that you don't beleive using a harness bar is safe. And I heard you and the others in the previous post where this was discussed. You have done due diligence. We probably can agree that we disagree.


Quote:
Then you haven't been hearing our drums. 4-point systems (Schroth or otherwise) DO NOT PASS TZC/THSCC tech for that very reason you state.


As Rich pointed out your Tech Doc states otherwise. And the instructor I had at my first visit to RR was running that setup in his BMW. He is qualified as an instructor with Tarheels. And at the very least has driven Tarheels events with it. So that is not consistent.

You're absolutely right. I don't. However once again your docs don't say I have to wear what the passenger wears. It says provide equal protection. Both seats have both setups.


Quote:
If someone is instructor level or very advanced, then our hope is that experience will guide them in and out of situations where roll-over protection is a non-issue... we can accept those drivers accepting that risk;


That's a double standard and safety rules should be uniform across the board. Instructors do make mistakes too, no?


Quote:
Thinking it won't happen to you because the percentages are too low is naive in my humble opinion.


That's not what I said. It is a calculated risk I am willing to take.


Quote:
You are absolutely right. That's why I mentioned the high-speed nature of this roll-over. Low-speed roll-overs, in most solid-roof cars, would probably still not require a roll-bar. But you can't know when its gonna happen, or under what circumstances, so you must prepare for the worst. As far as the facilities, yes if any of the tracks we use got like that, we would not be going back to that track until the issue was resolved. Case in point is CMP. The row of trees along the pit straight collected one of our instructors during one of our time trials from the back side (track right from turn 11). Had he not been a C5 with factory side-impact beams in the doors, the outcome would have been much, much worse that just a bent car. We told CMP they had to install a tire wall or we would not come back, and they did, and it probably saved another member from having to use a body shop instead of some rubbing compound the next year.

Will you drive at Willow Springs without a roll bar after seeing that? If so, what will you do to protect yourself from getting in a situation where those ruts become a factor? Same applies to tracks with close walls... will you drop down to 7 or 8/10ths through sections with little or no room for error? Or will you go balls out because you're strapped in and confident?


No. Never had any intention to drive there. There are a few other tracks I have no intention of driving at either. Rockingham and Lowes. Unless it is in a Nextel Cup car.

This is where I find a serious flaw in this safety debate. You mentioned that at CMP you got them to put the tire walls in to make it a safer track so Tarheels would run there. That's excellent.

But then in turn you run at Rockingham. So you want a tire wall in one section of CMP or you won't run there. But then turn around and run at Rockingham were you are surrounded by concrete walls. And most of the participants are in street cars. And you just had 2 serious enough accidents there in your last visit. Rockingham is a big accident waiting to happen. I think you've only scratched the surface with the recent 2 accidents there.

And you're worried about me using a harness bar? That's really confusing to me.

Please don't take this personally, but there are plenty of clubs, local and national, that don't care what you do in your car, as long as they make their bottom line and you've signed the insurance waiver. They aren't thinking about the future of the sport, or their members. There are more and more popping up everyday too. Its up to you whether you want to run with a group thats adamant about safety, or a group that leaves safety up to the particpants.


I'm not taking it personally as a critical attack on me. I hope you don't take it personally either. Oh, I do agree with you on something. There are a number of clubs that just want money. The one that ran the event with your picture above is one of them. Hopefully they'll be out of business soon.

Stacy, your heart is in the right place, but I could not agree less with this statement. I don't believe that telling the student that they cannot wear the harness because of the instructor's refusal to wear it, makes both of them safer. I'm not even convinced that the harness makes anyone drive faster. While it may add some comfort, I don't feel like going out at 10/10 because I'm wearing it. It's still gonna hurt physically and in the wallet if I wad up the car. That's sufficient to keep me in check.


Mark, thanks for jumping in here. I was hoping we would get yout take on this. It's great to see that you agree with Stacy, me and others regarding the risks associated with harnesses used in the absence of proper rollover protection.

One of the things we have to count on when we run these events, is people using some common sense. THSCC/TZC is a fantastic group of people in this aspect; most everyone really listens when we tell them them something... especially the 2nd, 3rd, and 4th times :lol: Many more things go unsaid as just plain common sense. No one has to say "uh.. don't try oak tree at the top of 4th gear.. you ain't gonna make it." At Rockingham, common sense says "Hey.. those walls aren't going to move.. I better find the pace that I'm comfortable going, and stick to it."
To say that Rockingham is a more dangerous track than others is rediculous. Look at this years Fall Fling. How many incidents were on the first day? Somewhere in the vicinity of 10?? I guess VIR is just an accident waiting to happen.. better stop having events there too.

We're worried about you using a harness bar simply because at a very basic level, it is not as "safe" as using all factory equipment, or all "race" equipment. Don't be confused; be thankful we're so concerned about your safety!

I'm guessing the point about Rockingham relates to the walls, banking and either driver error or mechanical/tire failure and t-boning the wall at 100+ mph. The mathematical expectation of such an event is nasty...the odds are very low but the payout is extremely high. When you look at the loads placed on cars on the banking, especially the outside rear tire, one can almost envision the day after such a nasty event happens when the inquisition would start. Imagining that and working backward may lead to some simple but useful steps that could be taken such as a mandatory tech inspection of tires twice each day.

Chuck

P.S. Something very simple like a $10 sway-bar mount can easily become the critical path leading to a disaster on the banking. This part just comes to mind since on some BMWs it is a weak link, especially if there are aftermarket sway bars installed. The sustained loads coupled with some shock (i.e. bump) inputs could do one in resulting in that payoff. :cry:

While Synergy (nee G&W) run a good event, theirs is an open track day and as such is not a fair comparison to a more structured event such as an HPDE.

Im with Adam here as well. IMHO, Rockingham is a track that you have to know your limits and PLAN how to drive it SAFELY. Also to draw a conclusion that Rockingham is UNSAFE fromt he 2 unfortunate incidents last month is just flat wrong. 1 was caused by the red mist, that can and does happen ANYWHERE. The other was a rookie mistake that was truly unfortunate. That certainly doesnt mean we dont need to run there. Hell they have been holding HPDE's there since before you or I knew what the hell THSCC meant. I dont hear tales of massive destruction, if that were the case, Im sure we wouldnt run there.

Graham while it's certainly your choice at which track you choose to run, your view of the danger involved at Rockingham is skewed IMO. Yes there were two incidents at our last events there, but the reasons for those had little to do with the track configuration IMO. The first one involved a driver that had the red mist (I've had it too) who was driving beyond his limits. That same result could have easily happened at VIR involving an Armco instead of the concrete wall. The difference is at VIR they charge you for damaging the Armco! The second incident was due to rookie mistake that ended up costing someone else's car. The car that was damaged was not at fault, again this could have easily happened at another venue. Barring equipment failure (as Chuck mentioned) I feel as safe at Rockingham as I do at VIR. Sure I could blow a tire and hit the wall, but that's a risk I'm willing to take. The same could happen to you at Roebling...a risk you were willing to take.

My point is that your chance of balling up the Vette at Rockingham is no greater than VIR or Roebling IMO. Like Adam said, common sense tells most people that you can't enter NASCAR turn #1 at 140 and expect to make it. Drive within YOUR limits and you'll be fine almost anywhere.

PS. I can take NASCAR turns 1 & 2 flat out... :D... but hey, I'm in a Cavalier! :wink:

I'll mention this again here for everyone's benefit...pardon if you've heard all of this before...just like you'll keep hearing "you are turning in too early" or similar instruction while screaming around the track in your car until you get it right, repetition of information is the best method of instruction...:D

Read the Tech Guide (and GCR where applicable) and ask our tech staff questions on an individual basis, by phone, by e-mail, or in person at a club function.

This is all very clearly written in the Tech Guide, pages 14-17, which describes the "rules of the tech road" for vehicles that are only being used for the HPDE portion of the event.

A 3 or 4-point Schroth belt that is DOT/FMVSS certified for the specific vehicle it is installed in (and that you have paperwork to that effect) DOES pass our tech inspection since it is an equivalent replacement for the stock DOT approved restraint system.

A "generic" 4-point harness, whether it is made by Schroth, Sabelt, or Simpson does NOT pass.

As it is currently written, you can use a competition 5 or 6 point harness provided that without ANY question it is installed in concordance with the manufacturer and SCCA GCR, although it isn't the recommended solution for a non-rollbar equipped car for the reasons mentioned earlier in this discussion. In this case, harness bars are to only be used to guide/position the harness and are not to be used as mounting points for the shoulder belts.

If none of those options float your boat, use the stock system, provided that the belts and mechanism are in good condition.

One little exception I ran across last year is that if you have a vintage vehicle/one which didn't come equipped with restraints (eep!) - please talk to us ahead of time about what you need to do to make it safe for track usage.

As always...we encourage use of these forums as they are good for discussion. The bottom line is that you should contact a THSCC HPDE/TT staff member INDIVIDUALLY to discuss your concerns, whether by phone or e-mail, or in person, as a staff member is the one that will make the final call based on the written rules or at the Tech Director or their deisgnee's discretion where applicable.

Bottom line with all this safety stuff is a risk analysis. First risk analysis is the decision to drive on track in the first place. The next is what safety gear you are comfortable driving with (or without). From stock setup, to harnesses, to seats, to bars, to cages, to full on race prep.

From there, there are so many little decisions that can make a difference. I made a very bad decision to use some extremely old tires on Sunday afternoon since one of mine got flatspotted. That tire blew in the braking zone for the turn into the infield during my final lap of the TT. Fortunately that's where it happened... not 5 seconds earlier when I was going 105-110 in the banking. Had that happened, you guys would have been scraping the SM car off the outside wall. (It was the right side tire that went.)

I've driven at a lot of tracks since I started this mess in June 1999, including 3 different ovals (Charlotte, Rockingham, and New Hampshire Int. Speedway). The road course tracks include Watkins Glen, VIR, CMP, RR, Summit Point (regular and Jefferson). The only place I've hit anything in my time driving on track (started in June 1999) is VIR, to the left side of snake. You have to make the choice to drive within your limits at each track, and it will be as safe as you can make it.

My personal risk analysis is this question... "What kind of protection do I want to give myself if the worst happens?" Given that bad decisions (as specified above) and mechanical problems do occur, what makes me feel the best about my chances in a hard impact? I now have a fully race prepped car. I run it that way at HPDEs (without the suit and the window net). I feel relatively confident that if that tire had blown in the banking, and the car had had to be scrapped off the wall, that I would have been not dead. I'm sure I would have been hurting like hell, but I would have lived and not had a major neck issue (thanks to the Issac I now wear).

Everyone has to do their own personal risk analysis, and make their own decisions (within the rules) as to their own thoughts on what's important to them.

Last thought: There is a difference between a novice showing up with a harness and no rollbar because he/she doesn't know any better, and an experienced (autocross experience included) driver showing up with the same set-up having thought through the risk and made an informed decision based on their personal feelings on the risk to themselves.

Ummm, why is that again? That policy doesn't seem to make a whole lot of sense, and having rulings (for lack of a better word) available in a search would be a good thing.

Dave:

That may be true for you and I'm not saying what you said is not
true (for you) but that is not consistant with human
nature-or at least my understanding of Human Nature in general.

I have read SAE and NTSB papers of studies that support the notion
people take more riskes driving as the safety (or precieved)
safety) of the vehicle increases. One of the examples studied
was ABS equiped vehicles recorded more front end impacts than
non-ABS vhicles. The statictics were completly out of wack to the
expected results of the advanced technology.
The reason concluded was drivers talgated more as braking ability
improved. Humans take every inch and then some.

Other negative result studies were linked to the driving behaviour
resulting from the sence of security modern cars give in
EU countries as well (non US drivers).

NASCAR F1 drivers talk about this all the time, and not
just Rusty Wallace, it's going on a all levels
from day to day road driving to professional racing.

Put harnesses and a roll bar or cage in the car and, I put it
to you, 90 or more% of the people will "find" more speed
with no other changes- but this is getting a bit off the topic............................

Mark, I respect your opinion and experience with student drivers. You may very well be right. I specifically made sure that I only spoke for myself regarding the effect that safety equipment has on my driving. In a more extreme case, if I realized that I had failed to buckle my helmet while on track, I would pit immediately (has never happened, by the way).

In further support of your statement, I often think I have a somewhat different approach to HPDE and TT that is simply a function of how my brain is wired. That doesn't bother me a bit because I think my attitude is a safe and cautious one, Roebling two years ago not withstanding. :wink: I'm pretty sure my brain was disconnected on that one Saturday. Since then I have not put four off except in the entire contents of another 911's oil tank at a PCA event. Too bad that wasn't caught in a tech inspection. Fortunately I steered the car backwards into a nice safe grassy spot, avoiding the concrete barriers with no harm done. OK, maybe a change of underwear was in order.

I'm sure we've all had a moment like that. Maybe that's why you won't lend Stacy your nomex undies? :lol:
