I don't know, man. I can't claim to know your struggle, especially since you're on the other side of the world from me. I interpreted the prompt to how would I run my country and that country is the US. I live in a positively sprawling metro area, with no mass transit at all; You could spend 3 or so hours crossing it at freeway speeds, and even just going to the club is a half hour drive (or ridiculous rent). I work with a vulnerable population (the disabled), and literally their primary barrier to care/ work is transportation. If you don't have a car, your center of gravity shifts. Meanwhile, my area is defined by inner city poverty vs rich white people to who pushed further and further out from the city as black people also flowed out to the "near suburbs" in the 80s and 90s.

I'm not here saying that different regions or places can make better use of it, Im just saying, within the parameters of the prompt, in my place, the automobile and automobile infrastructure has been used, extremely effectively, as tool of segregation and for the enforcement of inequality.
