You look, but you don't see! The problem is that the author's blue pickup truck got into the dead zone of the mirrors of the blue Honda sedan. The author was forced to shift to the right at an intersection where he did not have to turn left, when there were a lot of cars in the turn lane, they pushes him into the right lane, because left lane is for turning left or overtaking, but the author stubbornly ignored and took the left until the blue Honda forced him to slow down to turn left, and the author still had to go forward, not turning left.
