Some will say that getting angry could get you killed...isn't that why you're irate in the first place? The person almost killed you once.
Very interesting point. I have often wondered after an altercation with a driver wether it was a smart thing to do or not. You have given me some clarity on why we do get SO ANGRY with drivers. If they hadn't cut us off, we wouldn't be aggressive, but in that second you realise (this is gonna hurt) and actually avoiding an accident is when the blood boils and cyclists react.
My brother and I both ride to work 3-4 days per week and at the end of the week we both have half a dozen stories to tell about near misses. Most of them are people not giving way (being impatient).
CHEERS.
