These are three points so keep your eyes peeled.
A vehicle in the left turn lane frequently works as a shield in an intersection. This can be as you are passing the turning car going in the same direction as you or when a car is turning left across your lane coming towards you.
In the first case the vehicle blocks a motorcycle from view until the very last second and then you see it, waiting to make a turn.
Keep a close eye behind those blockers as you come around them and you will get the highest points!
