This statement isn’t true. I’m neither a car owner or driver and I knew about the meeting.
I’m certain every USAC licensed car owner was informed by USAC about the meeting. I heard about the meeting via social media - a Facebook post I think.
What more is USAC supposed to do? If you want to make certain you are made aware of these things join USAC.

FC is NOT the end-all, be-all that some think they are. I'd be more worried about cockpit incursion than my head hitting the wall.
First of all, I'm a firm believer that it is best to have some sort of "mechanism" to keep the driver's head within the confines of the cockpit/roll cage at all times. I have concluded that the head nets provide satisfactory protection to achieve that goal. While not necessarily "against" the full containment seats I believe their current design could pose some hazard that they are actually attempting to prevent. As I read the SFI 39.2 specification, the head restraint is supposed to accept a certain load, imposed to simulate impact, with deformation to be limited to the specification. Essentially, what I glean from this is the seat head restraint/halo is supposed to be very stiff. My issue with this stems from research by Dr. Bennet Omalu that suggests that concussions are not only caused by outward impact but that the brain, which is suspended in a viscous liquid inside the skull, can "rattle around" inside the skull, breaking through the liquid and impacting the inside of the skull causing brain injury when the head is moving and suddenly stops, as if hitting the head rest during a violent episode. The padding on both the seat and inside the helmet cushion this to some degree but I'm not sold that the full containment seat prevents what I've described from happening and, quite possibly, might promote this type of brain injury. My opinion is that the head nets offer the same protection without as sudden a stop of the head thereby lessening the possibility of internal brain injury. There are other issues with the full containment seats that I question, such as cockpit egress in both an emergency (fire) and extrication after a wreck. I like the fact that the head nets can be easily removed to allow exit. I will say, though, that I am a fan of the shoulder supports and other aspects of the seats.
It is just my opinion that I would like to see more research done on seat construction with regard to head restraint before I spend the required dollars to get a seat that complies with the specification.
Tim, you make to much sense,lol most people that are making this mandatory has never been in a Sprint car or late model before , our sport doesn't care about concussions, if they did after a flip or violent crash they would do a concession protocol, just like any sport.If no ambulance ride to hospital nothing gets done to check it out,
No issues with the Newer Butlerbuilt seats! Check out the Slidejob! I had no issues with my regular Sprint Advantage seats either, since my first New one in 2003.

So Casey what you a saying is that ever USAC driver will either have to buy a new seat that is SFI rated or hope at a lesser expense be able to get their seat certified.
