The issue was thrust into the spotlight for a second time this year in Sydney last Saturday when Shane van Gisbergen was slapped with a five-second penalty that dropped him off the podium.
The infringement came after he had made light contact with Will Brown’s bumper on the final lap.
It was the second flashpoint of bump-and-run controversy for the year, Erebus having accused van Gisbergen of similar tactics in Perth.
In that case a post-race protest lodged by Erebus was unsuccessful.
Van Gisbergen stopped short of publicly attacking race control in Sydney, but made his position clear.
“I feel a bit like Newcastle, not wanting to say anything,” he said, a reference to the infamous silent protest.
“If they showed what went on the five laps before, the racing and what people got away with… it was awesome, but a lot more than what that last corner was. I don’t really know.”
