And although certain public transit projects have large initial buy ins they typically cost much less than normal car infrastructure as you can extract part of the maintenance costs from fees and the maintenance is generally cheaper for things like trams and trains.
Something I think more people need to mention about public transportation is, it’s not about being against cars, but being for more options. For instance, many of us have elderly parents or grandparents who are too old to drive anymore, so they must rely on friends and family to get around despite being perfectly healthy to walk. But if they have reliable and close by public transportation options, they could retain their locomotive liberty much longer into their twilight years, and the same could be true for all of us as we get older.
