Jason - At every track day I've attended in the riders meetings it is emphatically stressed that at no time do you ever stop on the track. Corner workers and medical personal will handle the situation.

I'd guess on that straight the speeds were 140ish and 90ish into the left hand corner. Stopping creates a serious safety issue. Proper response is to slow and get your hand up and watch the corner worker flags. That was probably a red flag end of session condition.

In off road (wilderness, not track) situations it's proper to stop and assist if needed.

That makes sense. Like I said all my experience has been off road. I don't think that I have ever stopped for anyone at the MX track. Out in the woods is a little different story. I think most of the times I've stop in the woods was just to laugh friends who laid it down and make sure they were ok.

I think the last thing I would want to do (besides crashing) is to stop on a open track full of 500+ pound, 150 mph rockets coming at me. And as a rider, I don't want any additional hazzards on that track. At those speeds things happen way too fast.
