I agree with Josh to a point, but drivers usually dont take the time to actually assess how fast something is coming toward them, imo. They simply see light(s), expect that due to the distance away it is that they have enough time to make the turn. So they approach, glance ahead, and instantly initiate. Happens to me a lot, whether riding or driving. I'm not saying the rider wasn't mostly at fault because of his speed, to move at that rate and rely on traffic around you to make sound judgement calls is foolish anyway, fun or not. I ride like everyone could kill me if they so desired, so defensively it is then....at all times. Right or wrong, I could care less since it's kept me alive this long. Be mindful and take care out there folks, shit can jump out from most anywhere and end you.
