i ran the crash truck last weekend for a different organization at pittrace. i had one pick up in T16 that resulted in a broken hip (from what i was told) from trying to overtake, or from being run off the track. there is YT video of it as well. for a track day that is basically the equivalent of a game of pick up hockey, it’s not worth it.

go to the 7:50 mark. it was the first session of the day in A group.
that wasn’t the only incident on that portion of track. the other incident resulted in a broken back (again from what i was told) from one rider (who walked away) rear ending another rider which resulted in the supposed broken back. that crash also involved a life flight. i do know that it was a result of being rear ended because the rider who hit the one that got hurt told me that is what happened.
