I didn't bother to tune in for the first half of the race so I missed this whole fiasco.
I don't see anything wrong with black-flagging cars that are at risk of dropping debris but that rule hasn't been applied constantly in the past. In 2021 Chase was allowed to run several laps at the Roval before his bumper finally fell off and brought out the caution.
What is strange is that apparently Williams was called straight to the garage.
I absolutely understand his frustration and as a side effect he got himself some exposure that he never got before in five years of driving mid-pack Xfinity cars.
