This video, made by David Hembrow, a British citizen in The Netherlands, shows the growing chasm between the critiques of "vehicular cyclists" and the reality of cycling infrastructure, particularly when we can see the best in the world. Many of their critiques are only relevant to the poor bike paths built in certain locales such as California in the 1970s. And the relevant critiques such as the risk of intersections have been addressed in different ways to create the safest cycling cities in the world.
The criticism against separated bike infrastructure is becoming increasingly muted, though there are still pockets in the UK and North America. Increasingly, however, planners are adopting Dutch and Danish practices and installing much better infrastructure in Portland, NYC, San Francisco, Vancouver, Montreal and elsewhere.
Meanwhile folks like Hembrow and Copenhagenize continue to sway people's opinions with straighforward examples of what is possible. One such "anti-segregationist" switched teams because of the evidence. Here in Toronto folks like James at The Urban Country has been doing a good job showing the folly our own prejudices, even in bicycle-friendly Montreal.
