This classic StreetFilm by Clarence Eckerson, Jr., "The Case for Separated Bike Lanes" (original release date: February 17, 2007), is enjoying a renaissance this week. First, a post on TaketheTooker featured the film and sparked a discussion about the merits of bike lanes compared to riding in traffic. Then TreeHugger picked up the thread and posted a survey, asking whether protected lanes would encourage cycling. 

As of this writing, protected lanes enjoy a comfortable 73 percent approval rating, though the polls are still open.
