If the DB makes you angry.............you cannot prevent that from happening. An emotion, by definition, is not controllable. You can try to stifle the emotion and you may think that you're successful, but, in reality, you're simply suppressing it.

If the behavior frustrates a person...........as it does to me...........there is nothing I can do to prevent the frustration. I simply can refuse to act on it.

Is the DB worth a second thought............definitely not...........but, I'll be secretly hoping that he runs smack into a guardrail anyway.

I call that an attempt to control your emotions............but you will not have success in that endeavor, despite your claims.
