Great vid, thanks for posting. I remember when this happened.

Guy was clearly in the wrong (stepped out of vehicle and put his hands on her) and intended to seriously hurt her. I'm guessing he wanted to remove her helmet so he could start punching her.

On a bike you have to be super aware and it sounds like she was but then didn't change her behavior before the encounter and didn't use the advantage of the bike to get away from him. Once he got out, and she went kickstand down, her options were limited. She could have blasted the shoulder and been exits away from him the moment he opened the door. Of course she may not have known this would lead to a physical encounter either.

Getting away from a rager to deescalate as a first step is always a good idea and would help should something go to trial.

I have seen riders here in CO, in the passing/left lane, holding up traffic. Not 100% sure that was happening here but she said she was leaving a lot of room so she didn't have to work the gears. This isn't smart because it does lead to aggression and then it's you on two wheels vs car. I'm not saying that justifies his behavior, just that as a rider you are always going to lose a contest of mass, so I always try to avoid provoking one.

I do think lane splitting should be legal when traffic is stopped and can be safely done. She mentions that a lot of other riders in WA do this which gets them out of stop/go traffic.
