I had a close one yesterday too, 3 lane highway with another merging in and then merging down to two lane.
I'm in the 2nd from the left lane at about 65 when a ##**head in a jacked up, blacked out truck merging on from the other highway (accelerating) came across the lane to my right and tried his best to hit me on my right rear. Traffic was light so I was able to avoid him with some quick maneuvering.
He laid on his horn as he passed in the lane I had just swerved out of like I was in the wrong .....
The bad part was I just put a dual camera DVR system on my wife's bike the day before, and she wasn't with me to record the action.
Thank god for this super stable, highly maneuverable bike.
