The issue is that cars do not scale well. It's like running a tech company where IT manually triages every single ticket, with no self-service system: after a certain point, you just can't scale it up. Think of public transit, walking, cycling, scooters, etc. as the real-world transportation equivalent of automation. Cars take up a massive amount of space for a single person and dump tons of CO2, pollutants, and noise into their surroundings. And they routinely kill and/or maim people.

It's fine to own a car, park it in your garage space in a city, and use it to drive out of the city from time to time. It isn't OK for cars to dominate 50% of the space in modern American cities for roads, free street parking, and parking lots. Particularly because it comes at the expense of space that could be used for more scalable transportation solutions.

Sure, feel free to drive to the other city by car. But in a more scalable world without hellish traffic, you'll have to get around on foot, by bike/scooter, or using public transit in the city. Because cars aren't scalable.
