There's a difference if the same two people are in the car for 20 hours or there's three different pilots rotating.

The thing you need to take into account is that if an accident would happen because a drive fell asleep or just lost concentration, then you wouldn't want that kind of press. Circuit racing has all their paved areas, tyre barriers, etc. Rallying has lakes, trees, rocks and spectators.
