I think it's likely that the idea that bikes and cars don't mix will continue to pick up steam and cyclists will be less and less welcome on roads with cars in general, eventually leading to more and more prohibitions of cycling, first on "freeway-like" arterials, but eventually on all 35+ mph roads.

I believe the first priority of cycling advocates should be to do what we can to prevent that chain of events from occuring, starting with not supporting more and more facilities that reinforce the already too-widely-held notion that cyclists have an obligation to stay out of the way of cars.

I'd hate to dig up this post in 10, 20 or 30 years just so I could say, "I told you so".
