I’m not 100% sure but I think the rule is that if the driver gets out and the car is moved by another mechanism, the car is disqualified from further competition. A driver stuck in the gravel has to get out so the crane truck can move the car - so it’s an automatic retirement.
It could even be as simple as if the driver gets out, it’s done - not sure.
Yeah, I remember another race where 2 wrecked, one driver got out to check on the other driver then was gonna go back to his car but they told him he was retired from the race because he got out of the car.
And of course, now the race is red flagged for another incident. I'm turning in now. 💤
