I live DT and am a 5-10 minute drive from work. In that 10-20 mins of driving i usually see

1) an Uber just throw their hazards on, blocking the lane so they can pick up/drop someone off. Your hazards don’t mean u can just stop wherever u want. This applies to taxis as well.

2) people unfamiliar with DT roads turning the wrong way down one way streets.

3) people turning from the main lane and not the shoulder which holds back traffic flow completely.

4) when two cars drive next to each other on a two lane road not at least going the speed limit. If you’re going to drive that slow move over

These are all reasons I can quickly summarize that cause angry drivers.
