But with racing, you get an annual tech, meaning that the condition of things like brake pads, tires, bearings, are at the driver's discretion. Once you have your annual tech stamp, you just show the log book and your helmet/HANS to get through tech. That's one of the things that surprised me about racing. And the two times I went to DEs it was funny to have to have the car teched even though I could have raced it.

I spent way too many weekends at T1 at CMS. SCCA was the only show.... we ran safety at the club , IMSA and Nascar road races. I will never forget the SR on its top at T1 with gas poring down the driver neck into his helmet. He had installed his roll over valve upside down. We could not flip the car until the safety steward was on site. Long 3 minutes for that driver. The corners are now locked at most tracks. If you do not know what that means and track a car, you may want to ask the event chair. Expect a 3 minute wait after impact, before help is dispatched.

While there is a lot of good information in this thread, some things like expecting a 3 minute wait before help is even dispatched is not the norm for the PCA events I attend (referring to serious contact incidents)

My wife works for a small engineering consulting firm; the vast majority of their business is with the nuke energy industry. This conversation is beginning to sound quite a lot like what the nuclear industry goes through.
What I'm hearing is "the presumed disaster has such a high severity (if it were to occur in the first place) that no matter how low the probability, it's just not worth it". When designing a plant, the key challenge is (a) assessing the severity/impact of all potential points of failure, and (b) implementing an engineered solution which brings the probability of failure sufficiently low that the incident severity is no longer a driving concern. While cars are MUCH faster than they have ever been, there are certain realities we have to face (Greg succinctly called them out above). I agree that small, incremental, and iterative changes are the only way to address this; broad, sweeping sanctions like capping top speed will risk killing the sport if implemented too early. We also must look at the data (and do a better job of logging/tracking incidents). What is the TRUE probability of a Severity X Incident? How about Severity Y? Yes, driving is a risk. But so is bicycling in the city, or rock climbing, or playing soccer.

All good info. The compromise for some of us without the $850K when dealing with even a primarily track car driven to the track is one I've been wrestling with, especially after inspecting VG's solution and approach. I'd love to see a roll cage design with easy ingress/egress across the doors, like a removable door bar, but that is, of course, a compromise.

We are deep into this topic at the local club level. The discussions seem akin to ye'ol guns don't kill, people do debate.... Speed limits, IMO, would do little to address the more important issue of developing drivers that are promoted through the system when they've proven their ability to manage speed differentials through situational awareness and on-track predictability. It has to be a group effort from classroom instruction, to in-car and through observing group & individual behaviors on track. It's a continual process and something we are really committed to instilling in our members.

One thing that has been bugging me for many years is tires. Like other speed secrets, once your competition discovers them they no longer become an advantage.
Recently there have been a couple MotorWeek videos posted on these boards of track tests of cars from 30 years ago. When the test video of the 928 appeared, I got a call from the guy who drove my E-Production Golf 2 years ago on treaded street tires bragging how he had gone faster then the 928 at Summit Point. And trust me, he’s no Mario Andretti! Almost any seasoned driver could step into that car and cut another 5 to 10 seconds off his lap times. Part of the problem is that tire manufacturers want to sell tires. And to do that they have to provide tires that work better then their competitor’s tires. The result is that EVERYONE going to the track these days has better and much faster STREET tires then were available to any racer 30 years ago. With that technology in tires, lap times have decreased tremendously, and speeds have increased way past where a lot of people’s skill levels top out. Add the technology increases of the cars themselves to the better tires and even a bottom of the line grocery getter can out perform top of the line sports and performance cars from days gone by. Throw in a whole lot of nannies that do the driving for you and you really loose the ability to improve your driving skills. What all this means is that when things go wrong, the impact and severity of the incidents are increasing with time. Motor sports would certainly be more exciting if we went back to running skinny Michelin X radials to the cars like what was fitted to a new 911 in 1965. After all, when was the last time you actually saw a race car in a 4 wheel drift? That skill isn’t even in a driver’s tool box any more. The cars are hooked up all the time – until they aren’t and that’s when things are going really bad. |

My car has them and I don't feel particularly "at risk" for them being bolt in. Makes around town use less of a chore when out too. Seem to remember a '44 drover that had his door bars hinged so they swung open w/door. I think Charlie came up w/that option when he rebuilt his famous "stock" motor.

You don't race do you? You are in a four wheel drift nearly every corner. Its just not as egregious looking as is used to be as modern slip angles are lower. The skill is not only there, its even more refined than before out of necessity.
