For people here who are interested in transit, I highly recommend Jarrett Walker's book "Human Transit". He really focuses the conversation around a few ideas that almost everyone can agree on (and uses them to focus & have productive conversations in transit agencies) https://humantransit.org/

Last night I watched his talk "Transit Truths" - https://www.youtube.com/watch?v=k5AHJA2-lAc - which also summarizes the ideas in his book well.
