This episode discusses the history of the term "jaywalking" and how automobile interests overcame initial negative public opinion with marketing. Highlights include ladies beating police with parasols for telling them where and when to walk. I think you guys will appreciate it.
If you like this one, there's at least one more episode about transit if you look back in the archives. The show is about design more generally.
