Interesting that more than two years after this question was first asked, there is debate on the main site as to whether legal questions are on- of off-topic. Here is the question:
Bicycles riding in pedestrian crosswalks — Houston
One of the commenters states that he was voting to close because the question was asking for legal advice, and was therefore off-topic, and by the looks of things three other people to date agree with them, just going on votes to close. But I'm not sure that I can find anything within the Help section to say that, by its very definition, legal == off-topic. Is there anything?
I think legal stuff is very much like medical advice. I see no problem with general medical advice (e.g. will cycling make me fitter?), but I think we need to stop short at getting into specifics, e.g. I have a heart condition, is it safe for me to cycle?, where clearly professional advice would be appropriate.
So on that basis, I'm quite happy to get into a debate about whether cyclists should be allowed to ride on the pavement at an intersection (which is broadly what the question asked), but less happy to get involved in a kind of I-did-this-He-did-that-who's-in-the-right type question.
