Claire, I seen that just last night actually, funnily enough. The thing is, how do you know he won't get PTSD? It is still too early to tell whether PTSD is forming, is will become present. He may get it, he may not... depends how he viewed and perceived the accident to himself really. It is quite normal for them to live from those accidents. Those roll cages are often the most expensive part of those cars, for good reason. I have seen funny cars crash at those speeds, the driver walking away from it, all because of the safety protection they are encapsulated within. If you trust the rollcage, then you won't fear the crash as much.
