Something of a non sequitur on the commute home from work this morning. Was coming up to a large intersection with cars lined up at the red light. Worked my way up in between cars in the right turn lane and those in the right hand lane of travel. Came to a stop at the white line and dismounted, standing waiting for the light to turn green. I did not touch any cars around me to my knowledge. Gave a look around to see what the cars around me were doing when the Camaro immediately to my left surges forward while riding the brakes coming to a stop about two feet forward, the seeming universal challenge to race. The light is still red, left turn arrow almost finished. I stand for another second not sure what to make of this when the driver opens his door and is obviously shouting something, the only thing I am able to make out is "F-ing *****". Once I decide he is not exiting his car toward me I hop on the bike and pedal normally through the intersection on the green light. The black Camaro hangs back momentarily only to pass me on the opposite side of the intersection honking his horn and swerving toward me.
I do not know the driver, did not do anything I would consider inflammatory, genuinely confused as to what caused that outburst. Rode the rest of the way home laughing at the absurdity and trying to come up with a likely scenario. Any thoughts or similar experiences?
