Greatly appreciate help on both topics. We have an as of now undefined planes and automobile episode where the Nazi car projects could fit (including the construction of the AVUS track in Berlin and the construction Autobahn as well- although contrary to myth the Autobahn was not a Nazi project). That episode is currently scheduled for 1927 to coincide with Lindbergh, but we aim to cover a broader scope of transportation development for the whole period (we already covered the beginnings of the topic up to 1925 in the first 1919 episode).
I’ve added you to the TGIS Section 1 Group, where we will start collecting research and other contributions on an episode per episode level.
