All of these are our choices though. For instance changing taxation to make small, slow and pedestrian friendly cars way cheaper could have a drastic effect (some countries do). That can be combined with putting limitations on what category of vehicle can enter city centers. Introducing parking lot sizes privileging smaller cars etc. It’s all cultural, and either solution will take decades of effort, education, changing people’s behavior and costs tremendous money anyway.
