Test Video: For this blue flag test: 1) I chose Singapore due to its mix of both tight slow corners and fast sweeping corners. It also has two pretty good straights but is overall a power circuit. 2) I placed drivers in 1st and 12th to see the different effect of blue flags (passing back markers and being passed as a back marker) 3) I didn't push on strategies for lapping other drivers. Results: - 21 blue flag passes. - 3 of the 21 passes cost more than 2 seconds of time to be lost. - 1 of the 21 passes resulted in weird clipping through a back marker, no time was lost but it was a bit strange. - Of the 18 good passes time lost was between .5 and 1 second. - When shown a blue flag the driver looses between 1 to 3 seconds. Conclusion: Imo blue flags are where they should be, as a simulation they are duplicating real life blue flag although some of the time it may be a bit unrealistic. One could argue the simulation is getting realistic results due to imperfect AI instead of true simulation but I'm happy with what I have seen so far. Problems that still exist: - Still very hard to un-lap yourself due to blue flag triggering from a very far distance. - Cars still run out of fuel near the end of the race, although it is a bit less frequent.
