I instruct at Lime Rock for the SCCA driver's school. This year we had FV, FF, FB and FA out at the same time. We ride the students hard and we pound every bit of racecraft safety into their heads. Come the regional the next day, I know the students are the ones looking at the flag stations and checking their mirrors.
When I ran in the Skip Barber Series, many many years ago, we had morning driver's meeting that reviewed those topics as well as many track specific items.
I don't know where it gets lost. A project I will work on soon for the FV drivers is a guide so that if you go to a new track there will be no surprises. This will include corner stations, potential track problems, as well as anything else that I can think will make the racing safer and more enjoyable.
