Halo has been proven beyond doubt now, an essential safety feature. I hate to think what would have happened in the crash above without it. Next area that needs work is the safety of marshals. That’s an obvious fail this year that needs a huge spotlight shining on it until fixed.
I second that. As opposed to the drivers, marshals are hardly payed. I know, I've been marshal at rallies, a cup of coffee and a hot dog. They are suppose to run out on the track while cars are driving by, with no protection. Very dangerous.
