I obeyed traffic laws in general when I was a full-time bicyclist, because I knew how vulnerable I was to either hostile or inattentive drivers.
The only law I would’t completely obey was the stop sign. I wouldn’t absolutely stop, but I would slow down and ascertain my safety. I was never careless or chancy when it came to my road safety.
At one time, in my home state of Idaho, bicycles did not have to come to a complete stop at stop signs (lights were different). They did however, have to slow down, assess the situation, and proceed with caution (following the rules of stops signs when there were other vehicles on the road). Not sure if that has changed in 20 years.
