This is Archive.org's description of the video:
Interviews in public capture more than just a discussion of SUV's. Optimistic in the human power of the bicycle and pertinent in this violent political climate, Widdershins reflects on the connections between the shape of our world and the shape of our vehicles. A thoughtful voice-over and three years' footage are crafted in the organic manner of Ross McElwee's personalized documentaries. The film brings in to plain sight the insidiousness of SUV's, and creates a broader vision. It is timely, inquisitive, gently powerful, and honest.
