You either transport your body fast, or you are missing out. And the greatest thing to miss out is an opportunity. While programmers can live in one room for years and just use Zoom for everything, others can't.
Sorry to say, but most of my European friends who were much anti-car, have changed their opinion after... buying a car. Being able to move in whatever direction at whatever time and being able to carry some stuff in your trunk makes your life convenient. Add to that the privacy and your personal AC and you won't be able to top it off. In South Africa personal vehicle means security at night.
The only places where this works are the places where: 1. People live for retirement and pleasure. 2. The road infrastructure is just straight hell. (Like Portugal. It's bad in Lisbon. It is terrible in there). 3. Where you are not under any circumstances can be robbed by a random person on a street.
So, the so-called cars problem is not something solvable. You just have to handle other factors to and cars will follow. I've seen cities where improvement in economic and social conditions led to the development of nice pedestrian and bike infrastructure.
