Chicken and the egg. You can't really make people not want cars without better alternatives, which requires investments that aren't being made. I want a car, because I need a car. But put in a few bullet trains and offshoots, a business model for vehicles that enables access to a $100/month consumer fleet of shared vehicles so I can grab a truck, minivan, whatever as needed, and I will happily skip ownership.
This is a fantasy. In general, people don't want a shared vehicle. If they did, everyone would own a 5-year-old Toyota Camry, and not luxury pickup trucks, sports cars, Mercedes and BMWs, etc. The idea that these people are just sheep blinded by marketing is ludicrous.

I'm not going to debate that the Ford F150 dominates new vehicle sales in north America, but that's only accounting for the preferences of people who are buying new vehicles and doesn't track what the used market would buy if given unlimited options.
