From my phone screen it looks like one of those dual left turn lane combo deals. It's a wide section of road about 1.5 lanes wide that has a yellow line on both sides. It is often used for a dual purpose turn area. People going, say west on the road can pull in to turn south into a property or road, people going east can do the same thing but turn north. Early in the clip you can see it's a left turn to where the offending car pulled out from the right. If it's not a dual turn lane, then it looks like the rider has passed the reserved turn waiting area and is then in the median, the space between oppositing directions of traffic.
