In 100 years, we'll still be rich enough to afford cars, just they will be electric and self-driving. People only take public transportation because there's no parking, it's faster and/or cheaper, or they can get other stuff done while on it. All these being equal, people will choose cars.

You're kind of neglecting the advertising-led pressure to own a car. Car companies spend literally billions of dollars convincing you that cars are cool, and that they somehow indicate your status.

I see many people 'cottaging' in the summer. Drive for a couple of hours to a cottage, spend two days there, and drive back. It's not that enjoyable of an experience, really like owning two houses, that you need to clean.

I look at the pictures from 100 years ago of little resorts, and little resort towns. You take a train, spend a week in a pleasant atmosphere. Maybe you own a little cottage near the railway tracks, in a small village. It was more communal and more enjoyable. You can walk into the village in 15 minutes.
