Race distance
The lap count is chosen so that the race distance exceeds 305 km (Monaco excepted). High-speed tracks need fewer laps; tight circuits need more.
Two-hour limit
If the race hits two hours of elapsed time (extendable in some red-flag scenarios), it ends at the end of the lap when the limit is reached. Long suspensions can make this relevant in wet races.
Classification and half points
Drivers must complete 90% of the winner's distance to be classified unless regulations specify otherwise. Less than 75% distance completed by all cars can trigger half points.
