In the game, yellow flags flash on the steering wheel, the stewards wave green flags, and the monitors also display green. This is all unrealistic. In real F1, there are no flags on the formation lap (even in the rain)! Please fix this bug!

Also, the game should take into account fuel consumption on the formation lap.
