That's probably how it is. Kinda sad that the Spa version only has 24 slots even though there's two pitlanes, both of which are also driveable. Perhaps in a future update.Well, Si said we'd be using a safety car. And there's only space for 24 cars in the game. Unless the safety car is a also racecar that someone will drive, that means that one of those 24 spaces will be occupied by a safety car.
