Recently, director Fredrik Gertten traveled to Stockholm's Architecture and Design Center, where he gave a lecture on the battle for space in our streets and the motivations behind making BIKES vs CARS. You can see the full program here, in english with swedish subtitles. It's 40 minutes long, but worth a listen (bias aside...).
Fredrik's presentation was just one in a series of lectures titled "Cyklen och staden" or "The bike and the city." You can view all of them on UR Play.
