I’m not sure I’m understanding… as a driver you can legally pass by going into the opposing lane momentarily, as long as the line in the center is dashed (not solid) on your side and there is no oncoming traffic. That’s kind of the whole reason the center line is painted like that, combined with those signs that say “do not pass” and “pass with caution” when the line goes solid and back to dashed.
In that scenario, that would be part of the drivable area yes. However, that is exceedingly rare in the United States at least from my experience in smaller cities/suburbia (east coast). I regularly see people breaking the law by driving on the shoulder to go around someone turning left, and illegally crossing a solid double yellow line to pass a bicyclist.
In my experience in midwest suburbia the center line is almost always dashed unless there’s poor visibility (seeing around a tight curve or over a hill) or more than one lane of traffic in each direction (eliminating the need to overtake in opposing traffic). Or its a pedestrian zone, with reduced speed regardless.
True, some people break the laws. I don’t see it nearly as often as you claim to, and usually not in especially unsafe conditions, but the point stands that those people are selfish and impatient. I don’t see why bicyclists should have to sacrifice either their freedom (to bike to where they please and utilize existing public infrastructure) or their safety (by leaving the illusion that a full size vehicle might squeeze by at cruising speed) for such people. It’s not bicyclists’ fault that the infrastructure fails to serve all of its users equally.
