While I agree with you leardvr, in this case, I doubt any amount of runoff would have changed the outcome to this event due to the excessively high speed. I believe the car would have skimmed the surface of the runoff area just like those high speed boats do in the water when they lose control.
Once that chute failed, it probably destabilized that car to a point where it wouldn’t have been controllable and would have disintegrated just from rolling and rolling from the excessively high speed. I doubt if you had a 2 mile runoff that the outcome would have been any different. Just a longer trail of pieces and parts to pick up.
It truly is amazing how the technology of the NASCAR cars have come a long way along with the track safety improvements with the barrier walls that now take more of the impact with “give” but when you are talking speeds of 250+ mph, I don’t think we have that technology out there to save a human life should something go amiss. All thoughts of mine, nothing to back my statements naturally.
And like Needlenose said, why race if you are not going to speed
