In a race on Nordschleife/WTCC 2016, at 7 minutes and 55 seconds in first lap, while I was P1 I suddenly saw that the best time on this lap was 7.55. Then I saw someone in pits, I suppose it was the owner of this time and that he gave up the race and touched the finish line in pits (if it's possible...). I can't be sure as I didn't see if it was the same name as the lap time, but I don't have another idea. Next laps nobody recorded a "best lap" cause it was just unbeatable.
I noticed something similar on a MP-Race in Monza. Not fasted Lap, but as I was in the lead and suddenly there was someone 20+ sec. in front of me. Short after that someone was quiting the race...
