Fuller had some interesting ideas and thought about things that most people don’t consider (e.g., how much does a house weigh?), but the problem here, like much of the Dymaxion project is that it’s a complete break from the status quo in a way that doesn’t really allow for incremental change. It’s an early version of gadgetbahn: https://www.cat-bus.com/2017/12/gadgetbahn/
It's been a long time since I've seen text with encoding issues on a website, but somehow they managed to produce some there, at least for me: "For some time, I’ve been meaning to write about German transportation systems like what’s an S-Bahn or what’s a Stadtbahn." Still, interesting article!
