Populations either have personal vehicles or they don’t. For many of my neighbors, “choosing to drive” is an absurd economic proposition. This choice involves paying for the car, the gas, the maintenance, and the insurance, at the very least. Maintaining your privilege, avoiding tickets and accidents, all a delicate urban ballet.
Cars are often assets that will save and even help you earn money, but it is a very interesting thing when the upper classes are incentivized to give up vehicle ownership, or eschew driving. When cars are not saving money & time, they become liabilities, and a millstone around your neck. Some people feel relieved to get rid of them.
Many people love cars and love driving, but car culture was foisted on the unwilling public by the military-industrial complex. You drive cars and have highways because of war. Now your soccer mom drives a toddler munching tank to her jobs. Think about it.
For many people, choosing to be Taylor Swift would be easier than “choosing to drive”. It’s either public transit, or bike/walk/stay home.
Helsinki just completed a 10 km light rail line that cost ~€400 million, including some major bridges. That's maybe €10k per current and future resident in the areas connected by it to the city center. Spending that much for an option to have good public transit only makes sense if most of those people are going to use the line.
So most places either build less dense, or accept that wherever you go, there might not be parking spaces nearby. Which if you have public transport, often means its easier to park in some low cost P+R and take the subway.
