Blue Flags

Lapped cars don't hold you up, you just pass them.
In my case, usually just before a DRS zone :D

Backmarkers are incredibly annoying. Sometimes I'm behind one just before a DRS zone, go past and then their auto KERS kicks in to make them overtake me and hold me up a bit more. In racing this would see them be penalised!

I doubt this would be added to the current system, but it is needed on occasion. The thing with the auto KERS is if you pass them under normal speed then use KERS if then overtaken them again within 5 or so seconds they dont use it again and you are past.

Only time a lapped car holds you up is when they are on newer tyres than you.
If you see you are getting held up maybe you should use KERS to pass or just pit to get out of the way :)

Plus if theres a group of slow back markers (4/6 cars) you're pretty much stuck for like an entire lap maybe even more if your driver is stupid (I've had my fair share now) who doesnt overtake anything until it gets to the DRS zone. 

Or.... Your guy sits behind for a 3/4 of a lap for them to pass just before the DRS line and giving them back the place..

It is pointless to come here every other day and ask, if/when feature X gets integrated. Look at other threads in suggestions or bug section. There is rarely any reply from Jack. Maybe this feature makes it to his To-Do-List. Maybe not. We probably won't get any feedback. Sad but true.

It's almost September they are busy bee's with the updates.
It may only take 3 minutes to write a reply but them 3minutes are best used on updating info on the servers ;)

Blue flags means introducing Yellow & Green also, maybe a Black, Black & white and Red too :)

Black flag for not taking your drive through penalty within 3 laps of getting a Black & white flag & putting you out of the race :P

Red flag for when Double Yellows and a safety car just doesn't cut it, race will resume once the race marshals have cleared and fixed damage or maybe never restart results taken from positing of lap before accident :D

They should also introdue a little old hobbit to walk around the track, smiling and making everyones life's harder! His name could be Bernie Ecclestone!
