The compartment in this car looks like it held up well, especially with help from the cage.

OP, do not forget to replace the Hans straps to go along with your new helmet.
You post had me think back to two bad E46 wrecks I've seen and one I know of:

In one case the driver center punched the front end on the corner of a flag station. Massive damage to the front end, but other than a bit of a rippled floor, the interior was quite intact. Driver walked away. Seats, harnesses, cage, and I don't recall about the hans.

In another case, driver lost control and ended up going sideways into a concrete wall at high speed on the driver's side. He did not walk away and had serious injuries, but I believe most of those were from sudden deceleration. Seats, harnesses, cage and hans. Car was destroyed but the passenger compartment, while wrinkled, was intact. Driver eventually recovered.

In the one I didn't see, relatively inexperienced driver had an off with a street E46 with mods. High speed off into a flag station. Totaled the car car. Driver walked away.

Undoubtedly, the cages helped. Oh, about that always happening to the other guy. Literally just before the second case happened, the guy borrowed the air hose from the guy in the garage bay next to me. I hadn't seen him before or the car. The car was all gloss black and gorgeous. Not 10 minutes later that car was scrap and he was on the way to the hospital. Experienced and good driver that just had a bad day.

I hope I never find out how mine would perform...

However I would still leave open possibility that something had become weakened recently and went undetected.
This was a "grassroots" endurance race car, but I'm sure the car was prepped beyond many on the track. However, its not like the car is being torn down between races. Fatigue or small cracks can easily be missed. Wow, 100k spent on a "Lucky Dog" car. Times are a changing in budget endurance racing I guess.

There are a lot of them now, and it's a complex problem, and I can't help but wonder if we're headed for an accident like the Wannagofast one at one of "our" events someday ...
Psychology is a big factor in all of this. In addition to ignorance, there are also the effects of overconfidence bias and optimism bias, which *all of us* are susceptible to:

https://en.wikipedia.org/wiki/Overconfidence_effect
https://en.wikipedia.org/wiki/Optimism_bias

A remedy is to *assume* that bad things are just as likely to happen to you as anyone else, so proactive steps need to be taken to reduce both likelihood and consequences of incidents.

PS - Whenever this thread pops up on my screen, I wonder if the stock market is finally taking a dive in earnest.

Glad you are okay.
I've had a RTAB go bad on a E36 M3. Driving in the rain it was one of the scariest times I've ever had in a car.

I had a similar double whammy into the concrete wall at turn 16 Sebring in a spec E30 race car probably 10 years ago. The speed was probably similar to yours, and likewise the passenger compartment stayed intact, allowing me to walk away.

That'd be my guess if there were no marks on your helmet. I was knocked out when I totaled a 931 (front end, head on) and wasn't even wearing a helmet. I came to about 45 minutes after the collision in the ambulance on the way tot he hospital. There wasn't a mark on my head, the force of my brain hitting the front of my skull put me out.

Lucky you awoke!
I was at Le Mans in 2013 when Allan Simonsen was killed as his brain penetrated the sack.

Well, yes and no . It was 1993, I was at the top of my game. Everything in its own time I suppose.
