It depends on the track condition and as you mentioned track type, , it this case, wreckage is on the track so thus a stoppage of the race,, spin-outs and such where damage isn't present or the spinnee isn't in the way or likely to get clobbered get cut a bit of slack,, I agree it is different kind of race, more so for safety concerns and the layout of the track
C'mon Norm,
The 2 prior cautions were dumb and this wouldn't be happening if they treated them properly (blue flag, local).
Gee now it seems they have Terry mic'ed for sound. He's even embarassed to talk to 'em.
