Kindai is a biker. I'm not sure why he would have a prejudice against them. I also think it was the bikers fault and I am a biker myself (or at least I was until recently). It seems that quite a few of us bikers actually hold the riders actions to a higher standard than many non-bikers (I appreciate you also ride).
hence why I said "probably".. It was an assumption made given the quickness to blame the biker 100% as a few others have displayed.
However I now see that his quickness to blame the biker with 100% culpability stems from a blind assumption of what he can't see, what isn't in the clip and his opinion that the clip starts "conveniently" where it does.
To be clear, I do feel the biker in the clip was riding a little too fast given the traffic, the size of the road / available space to filter through traffic in and that it at least appeared to be a residential type area.
I would say based upon the clip as it's presented, it's 25% biker, 75% pedestrian. I do feel he was going a little fast for the circumstances shown, but it's very clear that the pedestrian made absolutely zero attempt to ensure the road was clear to cross before marching straight out from behind a stationary vehicle.
