Imagine a world that wasn’t built on the profit margins of petroleum refinement. No tires, no plastics, no bitumen; defaulting to some other mode of transport, not a state-subsidised automobile cult.
Another mode of transport will still be state-subsidised. That is what states do since Antiquity. Already the Romans invested huge money into ports and their famous road network.
Criticizing cars is fine, but "state-subsidized" is just superfluous there. This is not somehow unique to cars.
