It's long reads, but worth it. Had a very violent crash at Las Vegas (Thankfully nobody was hit by flying debris, though a few vehicles on the return road were damaged). Our former team mate sent us a detailed email about what happened, and it was not pretty. Said he thinks, based on what happened, a HANS/R3/ect would have saved him.
