Traffic makes a lot of people mad apparently. I get pissed off so easily in traffic and regularly (like once in 1 or 2 weeks) have short arguments. Sometimes I say stuff I regret and think "ok calm down, your reaction was too harsh". Like when I yelled at a man in a yellow vest who was telling me politely to get off my bicycle when crossing a bridge (you have to get off, it's the law) used by kids on their way to elementary school. He was there to make sure the little kids can cross the bridge safely. Only later I realized I have been a major douche. I was stressed because I was in a hurry. I planned to apologize to him the next time, but haven't seen him since. I swear traffic activates the evil in us.
