I would be awfully surprised if that van was doing 45, it looks like it almost comes to a stop at times. The thing the bikes did wrong was locking the rear brake, thats why they both stood up and both almost left the road...The lack of speed of the van makes it look far worse for the bikes than i suggest it really was.

Speed limit at the dragon is 30mph and that's optimistic for most passenger 4 wheelers. THat was the motorcyclists fault 100%.
Van in the front has the right of way, passing on double yellow is only allowed when the passer can do so safely. 100% the passers responsibility to complete the pass safely. The motorcyclist was obviously over his head, locked the rear brake, target fixated on the offroad solution, never a good thing.
I love the dragon as much as the next guy, passed on double yellow many times, nearly crashed a few times, but always respected the 4 wheelers. Its hard for them to get out of their own way. It will eat you up, not a playground, many 2 wheelers die there.
I was a little concerned that the van drove on, but with that many Harleys around, he was probably scared, and all those guys have cell phones so help would be there shortly.
