OTOH if the shoulder isn't rideable it's much harder to find a fair and reasonable compromise.
I've ridden just about every kind of road, both legally and illegally. To me it's not about the law or rights to the road per se, but what the road means --- the ability to get from one place to another. I'm all for the cyclist here if riding the lane is her only reasonable option. OTOH- If the shoulder is decent, and the cyclist is riding in the lane on principle, she has no sympathy form me.
I've used the word reasonable often in this post, and leave it to the judge to decide what and who is reasonable.
Fortunately, this kind of case is narrowly based and doesn't create a precedent that other courts and jurisdictions will follow. What would be sad and harmful to many others would be for this case to be a basis for denying cyclists the right to tide that road entirely (including the shoulder). If I lived there, and rode that shoulder, I'd be asking to speak at that hearing to ensure that that doesn't happen.
