I have banned cars on a number of my nations --somewhat on a whim, but also with slight hope that somewhere down the line this may lead to something interesting, policy-wise. So far, however, besides better environmental gains, I haven't seen any proposals for state of the art, all-encompassing public transit to pick up the slack and take its place... Is this going anywhere, or is it just a fun policy to have temporarily until further issues down the line allow you to reverse course?
Thanks for any help.
