I am with Jake on this one.
Maybe because of our common training: Keep Right Except To Pass
The guy could have/should have pulled to the right lane when he cleared the first knot of traffic.
We cannot see how long the guy on the bike was sitting behind the car with the camera.
My rule is: If you have someone wanting to get by, Let them by. The sun does not shine out of your back passage. Share the road.
The car driver's behaviour contributed to this incident.
Having said that, the guy on the bike is a clear Darwin Award candidate.
