There’s always a fine line between letting someone know your on their rear (especially for me because I have to do it through corners) and being dangerously close. The entire time I was out there, I never felt anyone crossed that line, which was awesome. I’m glad to hear that none of us put you in a nervous situation!
At one point (and I apologized to him afterwards) the Audi (sorry, don’t remember you rname!) caught up to me, but was hanging a bit back, so I thought maybe he didn’t want to pass. After about a lap or so of indecision I backed way off and let him pass. I just wasn’t sure what his intentions were, so it’s good to be nice and clear with your driving when close to someone else.
