Gregg,
In your opinion, is this problem (basilar skull fracture injuries) worsened by the presence of concrete walls so close to the track? I.e., would the old fashioned tire walls do a better job of protecting the driver by dissipating the energy better?
Note that NASCAR is scrambling to install SAFER barriers at all the tracks to prevent the cars from hitting the concrete walls.
From a personal basis, once the concrete walls went up at Road Atlanta I stopped racing there and won't race there. Other tracks in the SEDIV (VIR, Kershaw, Roebling) don't seem to have the car-destroying reputation that Road Atlanta has and we came very close to losing a driver as a result of those concrete barriers, in my opinion.
Just some random thoughts and questions that have been running through my mind...
