That won't buff out.
Comments said everyone lived through it at least.
Yes, everyone walked away.
What I captured, the guy looking back and hitting the tail of the bike before him, was a track controller.
I didn't see him look back anywhere close to the time of the incident.
There was a waving red flag, and I think the guy in front slowed quickly and changed his line.
The red shirt was indeed a control rider/instructor.
You're right, he wasn't looking back at that time.
