I had a guy doing that to me at an event a few years ago. I was in my C5 and he was in a late-model TransAm. I was really trying to focus on the right line, braking points etc. -- - This guy would just about lose it in every corner, then drag race down the straights (he could outpull me in the straights). Every corner I would have to avoid hitting him.
Thankfully he was spoken to about it after that session and moved to a different group. It was frustrating.
I need to get my car done so that I can come play again!
The Vette is awesome! When is her Birthday? - - she'll be asking for a Mast engine!!
