Nathan Robinson and Aisling McCrea speak to a very special guest: urban planning and infrastructure guru Justin Roczniak, who makes Youtube videos on planning, politics, transport and much more under the handle 'donoteat'. Together, they discuss city design, the human cost of architecture, trams, Who Framed Roger Rabbit, yakuza construction schemes, the psychology of driving, and trains. We love trains. Also, he informs us that all your furniture is made of stuff that catches fire really easily.
