The U.S. would drive you mad. Pun intended. But yeah, there's a lot of bike lanes without car/bike separation in U.S. cities. The best (worst?) example of this are lanes with sharrows.
This is madness for cyclist and driver. As a cyclist, I don't like basically taking up the whole line by riding right over the sharrow, which is what I'm supposed to do to avoid being doored. But then a car can't legally pass if there's a double yellow line. And yet they do pass in the U.S. in this case, because the average U.S. driver doesn't know this is illegal, they don't know it because the primary means of learning to drive: parents or family member > other people honking at you and you decide to change your behavior > traffic tickets. There's no mandatory 3rd party (government or private, accredited) school.
And on top of it, everywhere else there are no sharrows, increasingly people think cyclists are riding on those streets illegally, which is not true.
A motorist going 10 mph on a 30 mph speed limit street isn't breaking any law, neither is a cyclist. Driving slow on a single lane road is not impeding traffic anymore than red lights, yield signs, or left hand turns are impeding traffic.
Yeah, in California it is similar except you need to use the bike lane if there is one and it is safe. But you are allowed to leave it for debris or other reasons. On single lane highways with no passing lane, if 5 or more cars are behind you, you are expected to turn off so they can pass. But most will just illegally pass.
