At the risk of getting yelled at, some more info...
I'm not even gonna mention driver injuries, but they are what you would expect from a significant impact like this, fully expected to recover.
The Porsche had some sort of issue and was either trying to get out of the way, or get on pit road.. whatever, the initial contact with the Porsche was the right rear of the Camaro, sending it almost head first into the wall at an estimated 100 mph. (think Dale Earnhardt here) The car then hit with the back end as well. All the safety stuff worked, the SAFER barrier, the cage, the crumple zones both front and rear. They all worked so well along with the cage system that the front and back windshields are in the car which is really remarkable.
At these speeds on an oval you don't get to make abrupt moves, so the original contact was unavoidable.
The impact was so loud that it sounded like a shotgun went off and got everyone's attention.
Seeing someone injured in a car that you work on is very sobering, especially since I didn't see the original impact with the Porsche and thought it was a right front tire failure.
That's the nuts and bolt of it and anything else you can contact AJ or Joe, I just wanted to clarify a few things mentioned, it was not a car to car contact, only.
So the take aways are these.
1. If you are having some type of failure, in the car, everyone tries to get off the track, sometimes it might be better just to ride it out to the end of the straight and park near a corner station.
2. Ovals are not forgiving. you can't make abrupt moves to avoid contact,
3. There were lots of right front tire issues, another Mustang also scraped the wall this weekend, from a tire issue.
4. If something doesn't sound of feel right, bring the car in, another competitor that hit the wall earlier said the lap before it felt "funny". that's the time to address it.
5. Wear all of your safety gear, and wear it appropriately, this car had everything in driver protection, but a lot of track cars do not. I would say that if you don't have a stock airbag/inertia reel system, you need a Hans device for sure, anytime you use a harness.
