Why is car different? I love train and tram (not so much bus) and would love to see them doing well, but I understand why people love car, and not only in less dense countries. Do you know that car ownership in Netherlands is on the rise? [0]. One of the reasons cited being people preferring cars as they get older.
If you want to advocate for public transportation, make sure you understand why people love cars, and strive to make public transportation suck less, primarily with flexible schedule, quicker, and more readily available.
