It's a little ironic that up (or maybe down now) the page is a thread about not using bike lanes, because, yadda yadda. For the record I love and use bikelanes daily. I just don't think it is worth a letter to anyone to complain about someone blocking it. By the time I register the obstruction I have already calculated a path around it that doesn't add a single second to the commute. There are far more dangerous realities of urban riding than blocked bike lanes. That's my take anyway.
