A "blue flag" system for AI cars on out and in laps

Multiple times I’ve had practice laps ruined by slow AI cars coming out of the pits. Is there a way to get them to drive off the racing line when cars on push laps are approaching?

Hello, race flags topic already exists.

I just want the AI behaviour akin to blue flags. They don’t need the flags, they just need to stay out of the way.

Of course we need flags, what about yellow and red?!
