CA has signs that say, "Bikes May Use Full Lane." Bicycles are vehicles that are held to the same laws as motor vehicles with the minor exceptions. They must ride as far to the right as practicable. That does not mean on the line or on the shoulder. It means as far to the right as the rider feels safe. Further, cars may not come closer than three feet of the cyclist's body. That means cars often cannot perform an in-lane pass and must change lanes to pass. Impeding traffic does not mean the cars behind must slow down and wait to safely pass. A minor delay is not an impediment. Have you ever stopped at a stop sign or stop light? That means you have had to wait for other traffic - just like you have had to wait for people on bikes. It's no different. Every day Insee bad drivers on the road - and you have too. There are bad bicyclists and bad drivers. The bad drivers can kill a bicyclist. People who pass closely get the finger from bicyclists. I have never seen a bicyclist behave that way for no, unprovoked, reason. Go Pros are becoming very common on bicyclists and we are seeing more and more that drivers are way worse when it comes to dangerous driving around bicyclists than the other way around. Pass slowly and safely and be courteous and bicyclists will, almost always, do the same.
