A good article, thanks for writing it.
I'm not convinced that a majority of cyclists understand that they have to follow the same rules as motorized vehicles. It's unusual to see the driver of a car blast through a stop sign without slowing down at all. It happens, but not that often. On the other hand, it's unusual for me to see a cyclist who doesn't run stop signs.
I can see why: because you're going slower and have a full view around you. But that's still not an excuse if you're going to play the "cars and bikes are both vehicles" card.
