One step farther along the path to the root of the issue: Cars are incredibly expensive. That people in cities often choose to own cars and pay those prices reflects that they get more value from the car than the costs, often because alternative transport solutions are not cheaper, are way less time-efficient, and not nearly as convenient.

Fix that and many people will quickly pivot away from cars, reducing pull-through demand for oil, tires, brakes, lubricants, etc.
