The most dangerous place for cyclists is the middle of an intersection. Bicycles do not have A pillars, and thus no blind spots. If the intersection is clear, the cyclist should continue through without stopping to leave the intersection faster. Bicycles are slow to start, and can only take evasive actions while in motion. So its much safer to not stop.

Those laws are good and make cyclists safer. Some places may have different laws, but any law telling cyclists to stop at all stop signs should be disregarded. Ensuring your own safety is far more important than appeasing bureaucrats.

Edit: Just re-read my own local traffic laws and cyclists can legally treat stop signs as yeild signs here too!
