Starters and experienced drivers together will always give a conflict. The pro's will not take the time to wait until a starter is making a gap and otherwise the starter is very busy keeping his car on the track without knowing what is happening arround him.
It is important that race directors keep their eyes on the track and tell the drivers to make room or take care. Sadly today more and more tracks rely on the full automatic mode of RCM so race directors can walk arround and do some chats.
