DRS should not be possible out of the designated DRS zones. Not in practice or qualify. Now it's super annoying that the AI is deploying DRS on every straight. The track textures/materials could use a bit more contrast too, it's a bit washed out dark grey compared to the cars that have real blacks, that populate the same space.
DRS is getting deployed after 1,5 lap instead of after 2 laps. Looks like the minimum crossings and RearFlapZone Sessions are off.
I want DRS enabled. But in all sessions at the right place not everywhere. RearFlapZoneSessions=31 schould fix it.
