At 11.32 the NA 10.5 final, BOTH cars leave before the tree comes down, or even before the right lane was fully staged.

They gave the race to the car last to leave. But as I understand it, BOTH cars could have been disqualified per NHRA rules leaving before the tree is activated.

In any case, a weird final round, decided not by a race, but by the race director.
