If only one person has not advanced to the Feature Race when the Consolation Race(s) are reached, the Consolation Race(s) will be skipped.

If nobody is actively competing in a Race Session in a Heat Racing event, that particular Race Session will end early, so that the Heat Racing events can continue.
