Hey Chills,
Two out of three ain't bad
. Glad you had fun. I am sure you learned a lot. Learning to communicate effectively as an instructor with someone you don't know at 100+mph is surely as challenging as learning to drive the line smoothly. Some instructors are better than others. Sometimes you just have a personality conflict. Any time I get mixed commands I pull in the pits for clarification and we verbally walk through the rough areas. Then back out to try it again.
In our region safety always comes first. If for any reason the driver/instructor pairing isn't working you can always come in the pits and request a change. You may lose a run group but will have a better experience overall. Other regions may do it differently but I think it is standard practice with the PCA. Good luck your next time out.
