An instructor isn't always going to be a contant backseat driver and some may not be very adept at passing on immediate input to their students.

Just pointing out for the noobs that there are cues they can look for when they start out so they can figure out some things on their own even when the situation might have them a bit flustered.

For example, before my first time at Sebring I studied the map for days just so I would know the course like the back of my hand even before I rolled out on the track. That being said once I was out there and I was dealing with that first giant dose of adrenaline I did a lot of reading of the track and the cars ahead of me so I could be competitive but not get myself into trouble either. We are talking an intuitive art, not paint by numbers here after all.
