I'm normally a fairly easy going person, especially on the roads because I want to enjoy my commute. If someone does something silly or thoughtless, I usually see what is going to happen, avoid it and continue onwards without getting all worked up.
People doing something intentionally are treated differently.
Motorists (imho intentionally) cleaning their windscreens as they overtake are becoming increasingly and annoyingly common. The next one is going to get a big gob of spit in the passenger window, open or closed, if it is unlucky enough to be caught at the next traffic light. Grrr! 🙁
Serenity now!
