When the leader completes the last lap of the race, and crosses the finish line, the race ends. Any remaining cars on the circuit race to the finish line and complete the lap they are on. If they are also on the lead lap, they are scored as being so many seconds behind the leader. If they are not on the lead lap, they are scored as being so many laps behind the leader. Any cars not still running are normally scored as "retired" (Ret). If they have completed 90% of the race distance, they scored with a finishing position.
