you will get better at coping. the drivers on your route will get used to you. a strobe on your left drop bar will help, I noticed more courtesy room since I added mine. keep in mind our challenge coping with bike rage includes our increased physical and chemical changes that may be different that a cager's. meaning we are all hopped up on adrenaline and endorphins that a threat to our life triggers a fierce reactions, and coping with that is a challenge. I remember once, during a kill-zone interaction with a buzz-by I was so charged that I did the rest of that zone including an uphill section in top gear and then proceeded to reach my highest commute max speed after turning off onto a gentle downward slope. if I had been given the opportunity for a face to face interaction I might have ripped the guys throat out. I've caught up to few drivers and given them a piece of my mind and it was never pretty. try to stay calm and use this line: "I have recorded your plate number and am going to report you to the local police dept." that usually calms them down :-)

be cool, not a fool
