Sorry...in Japan where they import all their old cars to NZ, you could get by without having one. The trains are clean and efficient, although there's about 122.4 million people living there on some tiny narrow islands.
Have you considered living overseas?
NZ has only 5 million people and our public transport, is pretty dire, although it is improving. I think the govt now wants to squash as many people as possible into Auckland so that we can get enough people/taxpayers to pay for public transport, or live in 20 storey high skyscrapers. If we had them, we could get to places via zipline. Everyone would then have special Spiderman powers to navigate the glass canyons.
