@PS - you mention about the "right to be there" - does the cyclist have the right to be there in that scenario? The lights are green and the car is indicating left in enough time before the cyclist draws alongside the car, but then again, the bike is in a bike lane, which begs the question - who has the right of way in that situation?
I feel the same as the general feeling above, which is that I just wouldn't have done what this cyclist did (not that I'm convinced they were wrong). What is not clear from the vantage point of the video is that the cyclist slowed down from their previous pace and was staring in at the driver of the car, which at the time appeared to be goading the driver into turning into him, but as PS has suggested, he might instead have merely been looking to see if the driver had spotted him. But if that had been me, I'd have hung back.
I felt quite sorry for the driver. You can probably spot that the driver then came to basically a full stop because he could see me behind him, but I wasn't going to repeat what I had just witnessed, and waved the driver round, because AFAIAC, that was the polite thing to do, since he was ahead of me. #NiceWayCode, and all that.
