I've been the driver in this scenario before. Came to all ways stop sign intersection of 2 one way streets. Stopped and watched traffic go on the other one way street, then my turn came up and I started to go...a bike then appeared out of nowhere coming through the stop sign without stopping. Luckily I was able to stop. Scared the sh*t out of both of us and then he looked at me like I did something wrong. If saving his life for doing something stupid was wrong, I guess I can live with that.
