For those not familiar with SDC it's open track most of the day but first 1 hour is split into 2 groups. Sub2 and Over2. The reason is to help manage traffic in the golden hour where track condition is most optimal and PB can be set. So imagine my frustration when I found a very slow and off pace car when I enter Sweeper during the Sub2 session that perfectly ruined my PB lap. Later I found out it was a new driver with instructor in car which make it even more unbelievable and almost ruined my entire day. I had to really tell myself to focus on driver improvement instead of lap time for the rest of the day in order for the trip to not be a waste of money and time.
