It is hard to say who is at fault from that little video clip, but I can definitely see why the SUV thought it was okay to go. There was a huge gap between the last car through the intersection and the next car coming. Should she have seen the motorcycle? Maybe, but without seeing the shot from the perspective of the SUV it is hard to say.

What I do see on the video is the motorcycle swerving into the SUV!?! He had plenty of room if he just stayed in the lane he was in while passing the video car. He had to go out of his way to swerve right into the SUV that would have been clear of the video car (and the motorcycle if he didn't swerve). Also, why was the video car so far from the car in front of it? If the video car was in the funeral procession, they should have been right behind the car in front of them, not half a block away.

In any case, I think it is really hard to say this is the SUV driver's fault. I bet 99% of people would have gone after sitting at that stop sign waiting for God knows how many cars that were clearly in the funeral procession to pass by. She finally gets half a block gap and decides to go... I probably would have to if that motorcycle was hidden behind the video car.
