The arising of arrogance

I'd like to share a situation that happened to me and brought me a question about this arising of arrogance. I was driving and another driver got mad at me for a not-so-correct maneuver I did. At first I felt a bit uncomfortable for making him angry, but quickly I felt more compassion for the fact that he was feeling anger than any other un wholesome state of mind. Until a bit of arrogance arose, when a thought appeared: I was able to feel in peace even though the situation, while he let that unrest him and feel anger. Is that arising of this kind of *arrogance* usual? How could I meditate upon it or think about the causes and consequences of it? The problem I have is that I *do* feel sometimes like I'm in a *better* path to happiness (that is buddhism) than others but that makes this arrogance appear.
