Automobiles are one of a key pillar of logistics. Getting things (food, medicine, construction materials, etc. etc.) to and from backbones like rail, harbors, airports etc. So even for those who don't own a vehicle or even want to own a vehicle, automobiles are still a vast net positive.
I'm not sure what the alternative would be. Maybe everyone lives in giant 10 million+ population cities that are all connected to each other by rail (and rail connects all airports, harbors, etc.) and then you have to show up at rail station to get your groceries or whatever else?
Personal cars are not the same as using them for logistics.
Yes cars/trucks/busses are still useful overall and are an incredible last-mile solution for freight.
But on a personal level, it means we all must live far apart and maintain our own individual vehicles, along with the average total costs of $11,500/year PER CAR. [0]
I’m not saying they should’ve even been banned for personal use - owning a car and living in a rural suburb should still be an option, but it is very expensive to choose that lifestyle.
However the auto companies on the early to mid 1900s had heavy influence on policy, even buying and shutting down their public transit competitors, converting cities into “car cities”. This is where it drove into “negatives outweigh the positives” territory. Everything before that was more positive, but this was a massive negative on society and continues to handicap cities today, making them expensive and even just dangerous to walk around (due to high speed roads and limited sidewalks)
