Interesting topic. I have not ridden in Portland, so I can't speak from experience. Overall, the city appears to be fantastic as it embraces cycling like no other city of its size in the country--go Portland. The vibrant bike culture there makes me want to move. On the other hand, Geller did not address Schubert's very specific complaint regarding problematical bike lanes as they hit intersections. Instead, Geller provides a rather general complaint and points to the overall picture of a bike friendly city.
Geller is not wrong, but his response is weak to me. Since Schubert has no reason to lie, his criticisms look valid. Why couldn't Geller concede that some intersections need work and make moves to improve the situation? Portland can be great cycling city, but that does not mean there is no room for improvement.
On the issue of cyclists' responsibility and vehicular cycling, I'm with dlambert. I certainly don't count on some strip of paint to solve all my safety issues, and when I'm in traffic, I assume all the cars have got my name on their grills. The right-hook especially is one I'm always thinking about as I approach intersections. I was almost creamed by an old lady when she pulled by me, gave a little toot of the horn, then cut me off hard! The pscyho bitty had somehow convinced herself that a horn toot is universal for I'm about to cut you off you cyclist fool. I slammed the brakes and almost went over the bars. I promptly chased her into the parking lot, cut her off and slammed my fist on her hood. Damn was I scared and angry. From that point on, I've been hyper aware of such moves.
