I have been watching the replay with the now available camera viewpoint behind JAIAE86's car. You see indeed that JaiAE86 is involved in several car contacts, but he is bumped himself by others as often or even more than that he bumps others.
Three or for times, he hits another (slower) car that comes back on the track or on the driving line, which should have given the priority to him.
There is one big bump he gives clearly, making another car get off the track, but that's because he had to avoid another car that spinned just in front of him.
The fight for positions 2 to 4 during about 10 laps was really great driving by all three.
By the way, I still am not convinced qualifying works without errors. It doesn't sound logical to me that JaiAE86 started at the 15th place. Or didn't he try to make a fast lap during qualifying?
