IMO.

he felt threatened, and had to run over those 2-3 bikes to escape, if you notice that immediately after this, he actually swerved to not hit some other bikes that were in the way, and while they were chasing him he didn't once try to sideswipe or ram any of the bikes that were chasing him.

it's a bad situation and there is a slim possibility that after initially hitting the bike that got in front of him and slowed down abruptly, that they MIGHT not have beat him to a pulp, common sense says they would have. Hell, even the dude in this interview talked about the original contact with the bike like it was the RR guys fault when anyone can see it wasn't.
