General Road and Highway Discussion

My guess: they are distracted and their eyes are off the road. They start the curve, but you can see that they keep tracking the same curve even after the lane straightens out. Because they're essentially steering through peripheral vision, they are maintaining their position within the right-of-way rather than within the lane markings, which are harder to register in peripheral vision. You can see that their position in the ROW once they are through the intersection is approximately the same as when they entered due to the presence of the ION tracks causing the driving lanes to shift within the ROW. As their vehicle starts tracking further left in the ROW even crossing into the right-most on-coming lane, they probably noticed in their peripheral vision and were finally cued to reorient themselves (their brake lights finally come on) but by the time they were oriented, they were unable to move into the correct lane.
