I watched that one over and over a few nights ago. Sort of makes me feel a little safer in my car. Held up better than I expected in a roll over. Of course your skull without a helmet might not do so well.
I was saying it would be worse for hitting the roof with a lower center of gravity...but you are right in that a CG that's not in the physical center of the mass usually indicates a higher moment of inertia, which is harder to rotate, yielding less rolls.
He rolled four times though, which was more a function of his speed than anything else. No such thing as clean physics.
Yeah, can't really calculate something like that with so many variables. Loose dirt to the side of the track could make it dig in more or less, the tire sidewall height and stiffness, a bug flying in front of the car that you hit...
I'm really surprised it rolled at all though. I guess that little hump/dip I saw did him in.
I have watched that thing over and over and over and it scared me pretty bad. I have a bar (single cross beam from passengers side) and it worried me. Do miata's roll during auto-x on pavement? I've never seen one, but I was curious. I have also been off a road course on wet grass/mud and just slid around and sloshed junk in the windows.
That one really scared be because of how fast it went from sliding to rolling and it didn't seem like there was much reason, but perhaps he made it to some rough ground really quick or cought on the edge of the pavement. I just couldn't tell and am not familiar with that track.
I also don't have a harness yet. His head was playing ping pong in there.
The way he rolled seemed to save him. He stayed towards the inside with his head bent downward. Seemed to have the harnesses in correctly, but who knows. I doubt he was without a roll bar, all the clubs I know wouldn't of let him race otherwise. Crashing sucks no matter what, and as long as his apparent health at the end of the film is indeed as it seems, that video does nothing but boost my confidence in our cars. Double points for using a turbo related word in that last sentence btw.
