While downtown, I was going straight through an intersection and someone in a Jeep Cherokee going the opposite direction was turning left across my path. Two cars went before him without incident, but then he turned directly into my lane while I was in the intersection! I braked hard, yelled "HEY! What the hell!?" and shook my head. The guy looked like he was noticing me for the first time.

I wasn't going very fast, either. There were a ton of people walking around on the sidewalks, so hopefully some of them will think twice next time they think the intersection is clear.
