I think issues with laws, police, accidents, etc. are still only a periphery issue in Portland, but I think they will start to come into the bigger picture of safety and legal rights. But that will probably take a lot, hopefully not too many more accidents or carnage. The lack of discussion over engineering and laws of the recent two fatalities (right hooks in BL) is disturbing, and I'm worried it will take more such accidents to stimulate some real discussion. The BTA is also very pro-bike lane, to the point that they've made some serious mistakes with their implementation. A number of their projects are "complete-the-streets" type, where they want to throw bike lanes in everywhere. One particularly dangerous one is on Hall Blvd. decending SE towards Greenway. They put a narrow bike lane (a number of years ago) on a ~6% downgrade and to the right of right-turning traffic (turning onto Greenway), insanity. Interstate road and Greeley is similar (not as steep) where Brett Jarolimek was killed. If you stay in the BL, you have to run a gauntlet of right-turning cars and trucks. Another woman was hit there a few weeks after Brett was killed and went to the hospital, and she claimed to have been riding pretty slow (~15mph). They closed Greeley after that (no right turns) to "investigate" the problem, but I think it should be pretty obvious. I don't think any of the motorists were cited, despite the strange yielding laws (John Allen describes this as elevating bike lanes to the legal status of crosswalks). You can't have BLs on steep hills, even AASHTO with it's overall weak recommendations regarding bikeway designs says a 4ft. wide bike lane has a designed speed of no more than 20 mph. That's not even considering intersection problems.
So we'll see, I might get more involved with the BTA to try and steer them away from the most dangerous bike lanes and designs and give some input, but just like on this board, it will probably be a minority viewpoint. As far as Oregon's laws, Fred Oswald (of LAB reform) gave Oregon a tentative D-rating for it's bicycle traffic laws (might be an F+) right now.
